panfrost: Disable frame throttling

The new frame throttling implemention interacts unfortunately with
pipelining, leading to fence fds leaking like crazy and ultimately apps
crashing quickly.

With this patch, apps still crash but not as quickly. We need to either
figure out the real cause or revert the core changes.

Nevertheless, we don't want frame throttling in the first place, so.

This commit does this by allowing both RGB and RGBA visuals to match with
EGL configs. We also expose the `EGL_MESA_config_select_group` egl
extension, which is similar to GLX's visual select group extension, to
allow the RGBA visuals to get less priority.

intel/fs/gen12: Use TCS 8_PATCH mode.

Reviewed-by: Francisco Jerez <currojerez@riseup.net>

intel/fs/gen12: Implement gl_FrontFacing on gen12+.

The bit moved on gen12 in order to prepare for dual-SIMD8 dispatch.
This implementation isn't an entirely complete as it only works on SIMD8
and SIMD16 and not dual-SIMD8.

intel/fs/gen11+: Fix CS_OPCODE_CS_TERMINATE codegen.

Apparently the ts_request_type and ts_resource_select thread spawner
message descriptor bits were removed from the hardware at least since
ICL.  Drop them in order to avoid assertion failures on Gen12+
platforms which don't have any encoding for this.  On Gen9+ these are
probably just ignored by the hardware, so this is unlikely to have had
any functional implications prior to Gen12.

v2: Mark TS message fields as non-existing in brw_inst.h on ICL. (Caio)

Apparently this field was removed on SKL, and according to the

ForwardMsg message. It is ignored for other messages. The BarrierMsg
