This adds an action to the Game List context menu that lets users link
save data from Eden to Ryujinx, or vice versa.
Unfortunately, this isn't so simple to deal with due to the way Ryujinx's saves work. Ryujinx stores its saves in the... config directory... in `bis/user/save`. Unlike Yuzu, however, it doesn't store things by TitleID, instead it's just a bunch of directories from 000...01 to 000...0f and so on. The way it *maps* TitleID to SaveID is via `imkvdb.arc` in `bis/system/save/8000000000000000/0/` and also an identical copy in the `1` directory for... some reason. `imkvdb.arc` is handled by `FlatMapKeyValueStore` in LibHac, which, as the name implies, is a key-value storage system that `imkvdb.arc`, and seemingly `imkvdb.arc` alone, uses. The way this class is written is really weird, almost as if it's designed to accommodate more types of kvdbs... but for now we can safely assume that there aren't gonna be any other `kvdb` implementations added to HorizonNX.
Regardless, the file format is ridiculously simple so I didn't actually need to do a deep dive into C# code... of which I can basically only read Avalonia. A simple `xxd` on the `imkvdb.arc` is all that's needed, and here's everything that matters:
- The `IMKV` magic header (4 bytes)
- 8 bytes that don't really have anything useful to us, except for a size byte (presumably a `u32`) strewn at offset `0x08` from the start of the file, which is useless to us
- Then we start the `IMEN` list. I don't know what the `IM` stands for, but `IMEN` is just, well, an ENtry. Offsets shown are relative to the start of the `IMEN` header.
* 4-byte `IMEN` magic header at 0x0
* 8 bytes of filler data. It contains two `0x40` bytes, but I'm not really sure what they do
* TitleID (u64) at `0xC`, for example `00a0 df10 501f 0001` for Legends: Arceus (the byte order is swapped)
* 0x38 bytes of filler starting at offset 0x14
* SaveID (u64) at `0x4C`, for example `0a00 0000 0000 0000` for my Legends: Arceus save
* 0x38 bytes of filler starting at offset 0x54
Full example for Legends: Arceus:
```
000001b0: 494d 454e 4000 0000 4000 0000 00a0 df10 IMEN@...@.......

00000230: 0000 0000 0000 0000 0000 0000 494d 454e ............IMEN
```
Ultimately, the size of the `IMEN` sits at 0x8C or 140 bytes. With this knowledge reading all the TitleID -> SaveID pairs is basically free, and outside of validation and stuff is like 15 lines of relevant code. Some interesting caveats, though:
- There are two entries for some TitleIDs for... some reason? Ignoring the second one seems to work though.
- Within each save directory, there are directories `0` and `1`... and only `0` ever seems used??? It's where Ryujinx points you to for save, so I just chose to use that.
Once everything is parsed, the rest of the implementation is extremely trivial:
- When the user requests a Ryujinx link, match the current program_id to the corresponding SaveID in `imkvdb`
- If it doesn't exist, just error out (save data is probably nonexistent)
- If it does though, give the user the option to use Eden's current save data OR Ryujinx's current save data.
Old save data is deleted depending on which one you chose.

So firstly, playtime code is moved to src/common and qt specific code to yuzu/utils.cpp.
The dependency on ProfileManager was removed because it was working properly on Android, and I think a shared playtime is better behavior.
Now, playtime is stored in a file called "playtime.bin".
JNI code is from Azahar although modified by me, as well as that I added code to reset the game's playtime which was missing for some reason on there.
Before this gets merged, I plan to add the ability to manually edit the database as well.
Note: Code still needs a bit of cleanup.

This is because the rightmost row is "extended" to the rest of the table, and add-ons have long names, play time doesn't need that much space.

This is part of a series of PRs made in preparation for the QML rewrite. this PR specifically moves a bunch of utility functions from main.cpp into qt_common, with the biggest benefit being that QML can reuse the exact same code through ctx passthrough.
Also, QtCommon::Frontend is an abstraction layer over several previously Widgets-specific stuff like QMessageBox that gets used everywhere. The idea is that once QML is implemented, these functions can have a Quick version implemented for systems that don't work well with Widgets (sun) or for those on Plasma 6+ (reduces memory usage w/o Widgets linkage) although Quick from C++ is actually anal, but whatever.
Other than that this should also just kinda reduce the size of main.cpp which is a 6000-line behemoth rn, and clangd straight up gives up with it for me (likely caused by the massive amount of headers, which this DOES reduce).
In the future, I probably want to create a common strings lookup table that both Qt and QML can reference--though I'm not sure how much linguist likes that--which should give us a way to keep language consistent (use frozen-map).

This creates a Desktop Entry file and a PNG icon for the entry when the
user right-clicks a game and selects "Create Shortcut -> Create
{Application,Desktop} Shortcut". This uses the current executable's path
to create the shortcut.

I'm not going to test FreeBSD, so I don't know if they follow

works there and let them enable it.

[REUSE] is a specification that aims at making file copyright
information consistent, so that it can be both human and machine
readable. It basically requires that all files have a header containing
copyright and licensing information. When this isn't possible, like
when dealing with binary assets, generated files or embedded third-party
dependencies, it is permitted to insert copyright information in the
`.reuse/dep5` file.
Oh, and it also requires that all the licenses used in the project are
present in the `LICENSES` folder, that's why the diff is so huge.
This can be done automatically with `reuse download --all`.
The `reuse` tool also contains a handy subcommand that analyzes the
project and tells whether or not the project is (still) compliant,
`reuse lint`.
Following REUSE has a few advantages over the current approach:
- Copyright information is easy to access for users / downstream
- Files like `dist/license.md` do not need to exist anymore, as
`.reuse/dep5` is used instead
- `reuse lint` makes it easy to ensure that copyright information of
files like binary assets / images is always accurate and up to date
To add copyright information of files that didn't have it I looked up
who committed what and when, for each file. As yuzu contributors do not
have to sign a CLA or similar I couldn't assume that copyright ownership
was of the "yuzu Emulator Project", so I used the name and/or email of
the commit author instead.

Follow-up to b2eb103829
This is the "Double-click to add a new folder to the game list" message
that shows up when users first launch yuzu and is most likely never seen
again. Previously this message was not re-translated.
This change adds two new context menu items to remove either the OpenGL or the Vulkan shader caches individually, and the provides the option to remove all caches for the selected title.
This also changes the behavior of the open shader cache option. Now it creates the shader cache directory for the title if it does not yet exist.
Causes a heap-use-after free reported by AddressSanitizer. This makes
use of std::filesystem::path, but due to that we have to use their
string() function which may not work for all characters.
Currently with programs that have a 0 title id, yuzu loads the custom
configuration 0000000000000000.ini for per-game configs. This is not
ideal since many homebrews share this id. Instead for these programs, we
load a config that is simply the file name and `.ini` appended to it.
Previously NAND/SDMC installed titles would open device saves when they are supposed to be user saves. This is due to the control nca not being read and thus returns 0 for both GetDefaultNormalSaveSize() and GetDeviceSaveDataSize(). Fix this by utilizing the patch manager to read the control nca.
