6e7bfab4bd RTech: major cleanup of pak globals and improvement
Add missing types to fully mapped out PakGlobals_s struct, which is a 13MiB+ structure! This covers the vast majority of the pakfile system which is why we had to change a bunch of stuff for this patch. This patch also comes with:

- Reversed 'JobFifoLock_s' structure
- Reversed 'PakTracker_s' structure
- Reversed 'PakAssetTracker_s' structure

Many globals have been dropped as they were covered by the large PakGlobals_s singleton.

The pak decoder logic has been changed up as well, we now use a decode mode enumerant which will make it easier to add in more decoders for the pak files in the future.

3b9626612f RTech: add buffered decompress function, cleanup and bug fixes
The pak_decompress callback has been fully moved to a dedicated buffered pak decoder function, also added descriptive error to the buffered pak encode function. Fixed a bug in the streamed pak decoder where the next required streamed buffer size would always be below actually required on any subsequent patch rpaks that are getting loaded. Also fixed assert in Pak_ZStreamDecode, as the inbuf position can equal total streamed size, but shall never exceed it!

1c2b02b972 RTech: cleanup ZStd pak decoder and fix bugs
* Pak_InitDecoder() now takes the output buf and mask as parameters.
* Pak_InitDecoder() checks if provided masks are a power of 2 (required).
* Pak_ComputeRingBufferFrame() now uses the bit mask instead of modulo to determine # bytes used.
* Fixed a bug where PakDecoder_t::bufferSizeNeeded could be bigger than the file stream, causing a deadlock.

e1c889719a RTech: properly implement ring buffer stream decode for Zstd decoder
The new decoder can now decode patched and custom rpaks files, all issues so far have been fixed. The code still needs some testing and bench marking to make sure

c4691448c1 RTech: initial custom pak compression implementation
Allows paks compressed with ZSTD, to be stream decoded at run time. Currently seems to work pretty good, but needs to be further battle tested + cleaned up still.
