Libraries: Improved libSceHmd stubs (#3442)

* Initial work

* More work

* More stuff

* Update hmd.cpp

* Separate Reprojection and Distortion functions

Mainly doing this to clean up the code, since these sub-libraries are fairly self-contained.

* Fix weird Git issue

* Improve error documentation

After thorough decompilation, it seems clear that Sony didn't really put much thought into how libSceHmd behaves with no headset connected.

* Fix sceHmdGet2DEyeOffset

* Update hmd.cpp

* Add sceHmdInternalGetDeviceInformation and sceHmdInternalGetDeviceInformationByHandle

Based entirely off decompilation, these two functions are internally the cause of much of my trouble with this library.
They're also called by libSceVrTracker, but I don't think we'll be LLE'ing that anytime soon.

* Cleanup

* sceHmdGetAssyError

Struct isn't fully decompiled, but since it goes entirely unused when PSVR is disconnected, it doesn't matter too much.
I'm pretty certain it's 4 floats though, based on what I've decompiled of this function.

* More organization and fixes

* sceHmdGetInertialSensorData

Behavior should be fully accurate, but I've left the stub log since I haven't decompiled the parameters properly.
Also gave NID aTg7K0466r8 a proper name, based on what I've seen while decompiling. It behaves identically to sceHmdGetInertialSensorData, but with a slight difference in the params used for an internal function call.

* Update hmd.cpp

* Revert name change

* Organizational changes

These two functions modify internal variables used exclusively by reprojection functions.

* Remove internal device information calls

* Log PSVR-related attributes from param.sfo

Would mainly be helpful for compatibility list moderation, since these notices will be much more reliable for games that crash instantly.

* Remove unnecessary includes
