This change moves the instance id gs_thread_payload constructor and
lowering code will simply use that.
Also, this change takes the Xe2 register width in consideration that
fixes a couple of tests involving geometry shaders with gl_InvocationID
on Xe2.

The way this was implemented wasn't optimal. Compiling a functrion for
each lp_static_texture_state/lp_static_sampler_state/sample_key
combination is not great. This patch tries to contain the combinatory
explosion by compiling sample functions on demand inside the shader,
caching them and moving them to their intended locations when no chader
is running.
Improves CTS runtime by a lot.

The current implementation has many different code paths which get very
messy to reason about and maintain.
- FIFO mode worked well enough.
- IMMEDIATE did not need a thread at all, but present wait
implementation complicated a lot of things since we had to handle
concurrent special event reads.
- MAILBOX (and Xwayland) adds even more jank on top of this where
have present thread, but no acquire thread, so there are tons of
forward progress issues to consider.
In the new model, we have two threads:
- Queue thread is only responsible for receiving presents, waiting for
them if necessary, and submitting them to X.
- Event thread pumps the special event queue and notifies
other threads about frame completions.
- Application thread does not interact with X directly, only through
acquire/present queues and present wait condvar.
Two threads are required to implement IMMEDIATE and MAILBOX well.
IDLE events can come back at any time and the queue thread might be
waiting for a new presentation request to come through.
This new model has the advantage that we will be able to implement
VK_EXT_swapchain_maintenance1 in a more reasonable way, since we can
just toggle the present mode per present request as all presentation
go through the same system.
Some cleanups were done as well:
- We no longer need the busy bool. Since everything goes through thread,
we just rely on acquire/present queues.
- SW/non-MITSHM path is also moved to thread. Move acquire-specific
logic to the thread as well.

No driver supports urol/uror on all bit sizes. Intel gen11+ only for 16
and 32 bit, Nvidia GV100+ only for 32 bit. Etnaviv can support it on 8,
16 and 32 bit.
Also turn the `lower` into a `has` option as only two drivers actually
support `uror` and `urol` at this momemt.
Fixes crashes with CL integer_rotate on iris and nouveau since we emit
urol for `rotate`.

GFX10 has a hw bug and it can't handle 0-sized index buffer. The
non-indirect draw path was fine but not the indirect path where RADV
emits the index buffer.
This fixes flakes with dEQP-VK.*maintenance6* on NAVI14, and possibly
GPU hangs if there is an indirect draw with a valid index buffer right
before because it would re-use the same index buffer.

Similar to headergen2, the output matches as closely as is reasonable.

Track the files we've parsed, and skip ones we have already seen, if
(for example) we see the same paths imported from imported files.
Additionally having the list of files we have parsed will be useful to
generate a headergen-like top-of-file license comment.
