The fast path is the only focus of optimizations, so let's stop using
the slow one if the fast path is allowed. Only display lists with drivers
lacking draw_vertex_state use it, and drivers not exposing
PIPE_CAP_ALLOW_DYNAMIC_VAO_FASTPATH use it.
This changes gl_constants::AllowDynamicVAOFastPath to UseVAOFastPath
because it's no longer turned on/off dynamically, but only one of them
is always used per VAO. It also removes the IsDynamic and NumUpdates
fields of VAOs.

In the code path without arguments it tries 3 different paths and error
messages are overwritten one by other, in this case any of those
error messages are irrelevant.
For the code path with arguments is similar, as it already have a
fprintf(stderr) in the caller of open_error_state_file().

Meson complains:
../src/intel/decoder/meson.build:67: DEPRECATION: Project uses feature that was always broken, and is now deprecated since '1.3.0': str.format: Value other than strings, integers, bools, options, dictionaries and lists thereof..
So instead of trying to format a file, change gentest_xml to store just
the string. Need to adapt genxml_path to consider the current source
dir, but everything else works like before.

Both are deprecated and the alternatives are already being used in

With TES, the primitive ID is an input variable but it's considered a
sysval by SPIRV->NIR. Though, its value is greater than
VARYING_SLOT_VAR0 which means its location was adjusted by mistake.
This fixes compiling a tessellation evaluation shader in debug build
with Enshrouded.

In the past, we didn't have a good solution for combining scalar loads
with a variable index plus a constant offset. To handle that, we took
our load offset and rounded it down to the nearest vec4, loaded an
entire vec4, and trusted in the backend CSE pass to detect loads from
the same address and remove redundant ones.
These days, nir_opt_load_store_vectorize() does a good job of taking
those scalar loads and combining them into vector loads for us, so we
no longer need to do this trick. In fact, it can be better not to:
our offset need only be 4 byte (scalar) aligned, but we were making it
16 byte (vec4) aligned. So if you wanted to load an unaligned vec2,
we might actually load two vec4's (___X | Y___) instead of doing a
single load at the starting offset.
This should also reduce the work the backend CSE pass has to do,
since we just emit a single VARYING_PULL_CONSTANT_LOAD instead of 4.

From this we can see that we aren't doing more loads than before
and the change is pretty inconsequential, but it requires less
optimizing to produce similar results.

We need to allocate "shared size" bytes for each workgroup but
we were incorrectly multiplying by the number of workgroups in
each supergroup instead, which would typically cause us to allocate
less memory than actually required.
The reason this issue was not visible until now is that the kernel
driver is using a large page alignment on all BO allocations and
this causes us to "waste" a lot of memory after each allocation.
Incidentally, this wasted memory ensured that out of bounds
accesses would not cause issues since they would typically land
in unused memory regions in between aligned allocations, however,
experimenting with reduced memory aligments raised the issue,
which manifested with the UE4 Shooter demo as a GPU hang caused
by corrupted state from out of bounds memory writes to CS
shared memory.
