[Libs] Ngs2

[lzardy]

• Added all ngs2 related headers
• Reworked ngs2_impl to be more accurate, including structs (with byte comments, need confirmation)

I can remove the .cpp or .h that are not used or empty if needed.

Is this supposed to work yet? I tried with Resident Evil and it crashes when calling the module
shad_log.txt

[Lib.SysModule] <Error> sysmodule.cpp:sceSysmoduleLoadModule:47: (DUMMY) called module = ORBIS_SYSMODULE_NGS2

First off, let me state that audio in GR2 is a bit broken, and needs a skipped assert to get ingame, so it's possible that the problem comes from that, and not your PR.

Without the Ngs2 sysmodule, GR2 does output any sound, and with that on, the audio is way too loud and loopy. Here's a video showcasing it.

As the game does not go ingame on the latest main yet, I merged this PR on my gr2-hacks branch to test it. It segfaults a few seconds into booting, with the following stack trace:
hostBufferInfo is NULL here:

shadPS4/src/core/libraries/ngs2/ngs2_impl.cpp

Line 135 in 8d7d781

hostBufferInfo->hostBuffer = NULL;

called from here:

shadPS4/src/core/libraries/ngs2/ngs2.cpp

Line 192 in 8d7d781

result = SystemSetup(option, bufferInfo, 0, 0);

called from the game code.

I'll attach the log as well, with the last few lines manually copied over from the terminal, as those lines got printed out to there, but not in the log.
