📄 Description

Did a bit more looking into libSceRazorCpu and apparently the default behavior when the system hasn't initialized it with sceRazorCpuInitializeInternal is to just stub out every single function to return ORBIS_OK immediately.

Thus instead of pretending it isn't loaded, we can just add HLE stubs that debug log (to avoid spam) and return OK same as this default behavior, and everything works fine. This should help eliminate the log spam on some versions of PSPHD as well since it apparently does not check if the module is loaded. In the future we can also hook into these debug calls ourselves to add to our own debugging information.

Validated on Gravity Rush Remastered and Persona 5 Royal same as before.
