📄 Description

This PR implements sceGnmGetEqEventType and sceKernelGetEventData (called from the former, based on module research).

Games are normally expected to call sceGnmGetEqEventType to get the type of Eq/GraphicCore events returned from sceKernelWaitEqueue. Since this was not yet implemented, some games that would wait on a GfxEop event before rendering would permanently softlock.

Furthermore, equeue events are uniquely identified by ident and filter. Some code paths such as AddEvent were not checking on this.

Addresses a softlock in CUSA02168 (Gran Turismo Sport), CUSA24767 (Gran Turismo 7).

Needs testing.
