3f021404eb panvk/bifrost: Fix YCbCr texture/sampler array indexing 
When the number of planes per descriptor is greater than one, the layout
used on Bifrost doesn't work. Fix that by making sure all plane
descriptors are contiguous in the texture/sampler table.

072ea76a47 nvk: Implement ISBE space sharing on vertex stage 
When a vertex shader does not load any input attributes after any store
of output attributes, we can enable bit 25 of SPH ("ISBE space sharing")

Effectively this seems to allow input and output attributes to live in
the same allocated space in ISBE and could improve occupancy.

Found while researching geometry passthrough and mesh shaders.

60f6bd4761 kk: Clamp negative array indices to 0 
Required so that uint array formats don't incorrectly wrap to last array
slice instead of the first one. For some reason this only happens with
uint texture formats while int and float formats work as expected.

2e21eec921 radv/video: Fix num_ref_idx_l{0,1} related overrides 
Since we only support 1 L0/L1 ref, the default num refs in the PPS
should always be 0. With that there never any need to set the override
flag in the slice header (until more references are supported).
Also the ref pic list modifications should be clamped to the size of the
ref pic list.

This fixes an issue seen with dEQP-VK.video.encode.h264.i_p_b_13_*.

4711e5954e nir: Always use sysvals in lower_input_attachments() 
The last holdouts of the var options are gone so we can just emit the
system values.  This is overall simpler as it confines all the sysval to
var logic to nir_lower_sysvals_to_varyings().

0c36c39103 spirv: Emit SYSTEM_VALUE_LAYER_ID for fragment shaders 
We have nir_lower_sysvals_to_varyings() so we can just have that lower
it for the drivers who don't want a sysval.  Most have to support the
sysval version anyway for various lowering so making them all have to
support both is pretty annoying.
