gallium: add lima driver

v2:
- use renamed util_dynarray_grow_cap
- use DEBUG_GET_ONCE_FLAGS_OPTION for debug flags
- remove DRM_FORMAT_MOD_ARM_AGTB_MODE0 usage
- compute min/max index in driver

v3:
- fix plbu framebuffer state calculation
- fix color_16pc assemble
- use nir_lower_all_source_mods for lowering neg/abs/sat
- use float arrary for static GPU data
- add disassemble comment for static shader code
- use drm_find_modifier

v4:
- use lima_nir_lower_uniform_to_scalar

v5:
- remove nir_opt_global_to_local when rebase
