  [AMDGPU] NFCI: Track AV Register Pressure separately (#149863)

Adds new entries in the GCNPressure array for AVGPR pressure. In this
PR, AVGPR pressure is added to pure VGPR pressure under all the pressure
queries, so it is NFC.

Separating out this pseudo RC will help us make more informed decisions
in future work. This RC can be assigned as either VGPR or AGPR, so
tracking them as pure VGPR pressure is not accurate.
