- our logging code was bigger than spdlog itself, why???? just keep it simple
- fix issues when logging before logging system is even started
- removes the "initialized logging twice" issue
- removes uneeded indirection in file logging
- uses direct formatting instead of jumping hoopla-around the fmt::format() ressult
- code duplication and dead code removal as usual
I did explore dup2() but I think it's not worth the hassle
I did try `fwopen()` but it's better if things are just kept as-is.
there is a lot of noise because I removed a bunch of redundant files on logging and just put everything in one file
now normally this wouldn't be a good idea, however consider: the complexity of logging; it's less than 500 lines... does it really need a whole subsystem?!?!?! ITS JUST LOGGING

This PR introduces an optional Legacy Rescale Compatibility Mode that restores the previous rescale‑pass behavior for titles that rely on its quirks. While the new rescale logic is generally more correct, some games exhibit visual issues that the legacy behavior incidentally avoids.
Enabling this mode can mitigate line artifacts on AMD GPUs and reduce grey‑texture flickering on Nvidia GPUs in Luigi’s Mansion 3. This is a compatibility workaround rather than a full fix, and should only be used for titles affected by these rare edge‑case rendering problems.
Original Logic from MaranBR

Adds slow and turbo modes with configurable speeds that can then be
toggled by the user. Behavior is:
- Standard/slow limit, toggle turbo = turbo
- Turbo limit, toggle turbo = standard
- Standard/turbo limit, toggle slow = slow
- Slow limit, toggle slow = standard
Enabling the turbo/slow mode enables the frame limiter unconditionally.
This has some conflicts with VSync. For example when I set my refresh
rate to 60hz and enable vsync, turbo mode does nothing. Not sure how to
go about fixing this, @MaranBr probably knows better the proper
solution.

The GPU Accuracy level is now divided into Performance, Balanced and Accurate.
1. Performance prioritizes speed at all costs. It's faster, but it can be unstable and may have some bugs (which is expected).
2. Balanced maintains excellent performance and is safer against bugs and shader corruption.
3. Accurate is the most precise and the most expensive in terms of hardware. Only a few games still need this level to work properly.

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

```
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.
