Merge 9356b68f26 into 7085bafa60

Added functionality that allows ExeFS mods to compile to their own PPTC
Profile and therefore store PTC data between sessions.
The feature calculates the hash of the currently loaded ExeFS mods and
stores the PPTC data in a profile that matches said hash, so you can
have multiple ExeFS loadouts without causing issues. This includes
different versions of the same mod as their hashes will be different.
Using this PR should be seamless as the JIT Sparse PR already laid the
groundwork for PPTC Profiles and this PR just allows ExeFS mods to load
and store their own profiles besides the `default` profile.

❗❗❗ **WARNING!** ❗❗❗
**This will update your PPTC profile version, which means the
PPTC profile will be invalidated if you try to run a PR/Build/Branch
that does not include this change!**
**This is only relevant for the default PPTC Profile, as any other profiles do not exist to older versions!**
