Adds PIPE_CAP_PRIMITIVE_RESTART_FIXED_INDEX which is a subset of the
primitive restart cap for when the hardware can only support the fixed
indices specified in GLES.

The switch statements were automatically modified with this command:

find \( \( -name \*.cpp -o -name \*.c \) \! -type l \) \
 -exec sed -i -r \
 's/^(\s*case\s+PIPE_CAP_PRIMITIVE_RESTART)\s*:.*$/\0\n\1_FIXED_INDEX:/' \
 {} \;

v2: Add a note in screen.rst

Driver supports integer multiplication between a 32-bit integer and a

Accessing the TG4 component via immediates in the llvmpipe backend is quite
messy (like really messy). Roland suggested we change the instruction encoding,
so introduce a cap to allow the component to be selected to be store in the
sampler swizzle, which should be otherwise unused.

I could probably switch all drivers over, but virgl would need some work that
I'd prefer not to rush it.

For radeonsi, we will prefer the NIR pass as it'll generate better code
(some index calculation and a single load vs. a load, then index
calculation, then another load) and oftentimes NIR optimization can kick
in and make all the access indices constant.
