Lib.SysModule: Proper HLE implementation (#4102)
* Replace sysmodule enums with table

Dumped this from the 12.52 module, using a script I created.

* Better documentation

* Separate from system libraries

That system folder is going to be getting quite large if I left all the sysmodule stuff in there.

* More arrays from library

* Found another preload list

Ghidra really hates decompiling libSceSysmodule, so I didn't notice this one at first.
Also documented specific versions tied to each preload list.

* Start work on implementation

* Some basic implementations

* Initial stub for module loading

Just enough to see if the logic functions appropriately.

* Clang

* sceSysmoduleLoadModule

Now I need to get sceSysmodulePreloadModuleForLibkernel done so that we don't have bugs from not loading internal LLEs.

* sceSysmoduleLoadModuleInternal

* sceSysmodulePreloadModuleForLibkernel

I have successfully broken quite literally everything.
I shall debug this tomorrow.

* Slight fix

* Maybe fix?

* Change log

Enjoy the log spam 😄

* Increased defined stub count

Now that libc and libSceLibcInternal loads later, all the auto stubs are getting consumed by it.

* sceSysmoduleUnloadModule stub

Also a couple fixes. Sysmodule does pass argc and argv to game modules, but only after loading them once to check  binaries.
Shouldn't matter for the most part.

* Clang

* Less stubs

2 thousand is seemingly enough.

* sceSysmoduleLoadModuleInternalWithArg

Doesn't hurt to have, since Apex Legends calls it.

* Oops

* Oops 2

* Rename isModuleLoaded to getModuleHandle

Review comment

* Remove debug game module loads

These cases only trigger when specific sceRegMgr key values are set, and for our purposes, we can treat that case as false.

* Allow preloading to fail

For kalaposfos

* Clang
