broadcom/compiler: track partially interpolated fragment inputs

We will need these to implement GLSL's interpolateAt*() functions where
we are required to perform interpolation in the shader at arbitrary
offsets.

iris: Fix doubling of shared local memory (SLM) sizes.

Commit 67ee9c5f5537fe85357556a4322a07253d13a697 added support for
using the `pipe_compute_state::req_local_mem` field, because Clover
can have a run-time specified size that isn't baked into the shaders.

However, it started adding the static size from the shader to the
dynamic state-supplied size.  The Mesa state tracker fills out
req_local_mem to prog->Base.info.cs.shared_size, which is exactly
what we fill out prog_data->total_shared to be.  Effectively, this
meant that we double-counted the same SLM requirements, doubling
our space requirements.

Fixes a 10% performance regression in Synmark2's OglCSDof test.

intel/compiler, anv: Delete cs_prog_data->slm_size

cs_prog_data->slm_size is basically redundant with
prog_data->total_shared, which is the field that we actually use for
controlling the shared local memory size in all drivers.  We were
still using it in one place for VK_EXT_pipeline_executable_properties,
but we should just fix that and delete the field.

zink: redo slot mapping again for the last time really I mean it

now that shader compiling is happening all at once, we can store the slot
map on zink_gfx_program directly and reserve it dynamically in order to
use up only the slots that are actually being used across all shader stages

zink: add more explicit fencing for transfer maps

we're using our (primitive) buffer r/w tracking here to ensure that our
src buffers are synchronized before we do any kind of read operation on them

this is pretty slow in some cases, but it fixes a bunch of piglit tests

radv: fix ignoring the vertex attribute stride if set as dynamic

The vertex attribute stride should be ignored, so make sure it's
initialized to zero if dynamic to avoid computing a wrong offset.

The fact that each element of pStrides must be greater than or equal
to the maximum extent of all vertex input attributes fetched saves us
one user SGPR for the dynamic stride.
