📄 Description

This PR implements Gnm EOP event handling and support for GPU submitted flips.
The next functions were added

GnmDriver:

sceGnmAddEqEvent
sceGnmDeleteEqEvent
sceGnmInsertWaitFlipDone
sceGnmSetEmbeddedVsShader
sceGnmSubmitAndFlipCommandBuffers

VideoOut:

sceVideoOutGetBufferLabelAddress
sceVideoOutSubmitEopFlip

To maintain proper sync between GPU and presenter, a new entity Platform::IrqController was introduced.
