[core, android] Initial playtime implementation (#2535)

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.
