Annotating ssa defs without affecting compilation is impossible with
debug info instructions since referencing a nir_def from the debug info
instr will add uses.
The old approach also stops worrking if passes reorder instructions.
This patch proposes a solution which should not regress performance just
like the old approach. The difference is that this one allocates a bit
more space for debug info instead of adding a new instruction for it.

If the hardware does not support INSTANCE_INDEX natively, it will be
lowered to load_instance_id + base_instance. Otherwise, INSTANCE_ID
will be lowered to load_instance_index - base_instance.

NIR doesn't really support global instructions such as global val
initilisation. So here we add functionality to glsl_to_nir() to
put these instructions into a temporary function that will be
later inlined into main.
We give the function a name starting with gl_mesa_tmp_ as functions
starting with gl_ are reserved and will not have any clashes with
user functions, we finish the name with the blake3 of the shader
source to avoid conflicts with multiple shaders attached to a single
stage.

AGX has limited border colour hardware. To support full
customBorderColorWithoutFormat semantics, we're forced to emulate in shaders at
a substantial performance penalty. Actually, that's needed just to pass CTS
because of other hardware issues stacking on top of each others... Hooray!
Add the texops we need to facilitate efficient custom border colour lowering.
