rusticl support for v3d

Basically works.

Latest CTS run: Pass 2432 Fails 71 Crashes 0

known problems:

• PIPE_CAP_QUERY_TIMESTAMP for profiling support (36 fails)
• unnormalized image coordinates not implemented
• RAM shader cache broken
• some weird SIGSEGV on mapped memory
• variable shared memory
• CTS exceeds PIPE_COMPUTE_CAP_MAX_GRID_SIZE, needs lowered huge GRIDs (rusticl needs to lower this itself, WIP)
• synchronization issues with mapping
• something broken with 16 bit (12 fails)
• unaligned load/stores, porting fully to nir_lower_mem_access_bit_sizes (11 crashes)
• contraction failing due to unexpected flush-to-zero behavior (8 fails)
• nir_op_bit_count lowering missing in nir_lower_alu for 8/16 bit (1 crash)
• nir_op_fisnormal lowering missing in nir_lower_bool_to_int32 (1 crash)

Depends on:

• !25363 (merged)
• !27666 (merged)
• !29554 (merged)
• !29711 (merged)
