gnmdriver: Implement sceGnmSetGsRingSizes and sceGnmSetupMipStatsReport (#5179)

Browse Source 
* gnmdriver: Implement sceGnmSetGsRingSizes

- Match Sony libSceGnmDriver 1 MB alignment and [4 MB, 8 MB] range validation
- Return 0x08000000 on invalid size parameter
- Program Liverpool VGT_ESGS_RING_SIZE and VGT_GSVS_RING_SIZE registers

* gnmdriver: Implement sceGnmSetupMipStatsReport

- Match Sony libSceGnmDriver 64-byte alignment and 48-bit address validation (0x80000001)
- Validate report buffer size >= 0x1040 and (size & 0x7FF) == 0x40 (0x80000002)
- Zero output buffer and write 64-byte header size
