📄 Description

This PR does a few things:

Create a define for the latest firmware version number, this can be used in place of game firmware for sceKernelGetSystemSwVersion, and I used it for sceKernelGetAllowedSdkVersionOnSystem.
Fix get_authinfo with null authinfo struct. When I ran this edge case on my console, I got a -1 return with errno set to EPERM.
Stub sceKernelGetAppInfo, currently only populating the cusa name and has_param_sfo fields.
Implement sceKernelHasNeoMode, this returns true if you're running on a PS4 Pro (and doesn't require the param.sfo flag)
Implement sceKernelGetMainSocId based on hardware observations. This returns a chunk of data from a cpuid instruction, and is used by some libraries to determine if they're running on PS4 Pro hardware.
Stub sceKernelGetCurrentCpu, this is spammed by a few games.
