Disable mesh autostrip for platforms that need WA 16020916187.
Additionally, zero out the layer and viewport slots when a shading rate
is found through the brw_nir_initialize_mue pass.

The InlineData passed to the shader is a fixed size unrelated to the
register size. It happens to match pre-Xe2, but by considering it the
same in Xe2, we ended up reading pushed constants from the wrong place
when they didn't fit in the InlineData.

This intrinsic was initially dedicated to mesh/task shaders, but the
mechanism it exposes also exists in the compute shaders on Gfx12.5+.

In SIMD32, the fence instruction is currently going to read grf0-3
leading to such assertions in the backend :
../src/intel/compiler/brw_fs_reg_allocate.cpp:206:
void fs_visitor::calculate_payload_ranges(bool, unsigned int, int*) const:
Assertion `j < payload_node_count' failed.
The reason we haven't seen the problem yet is that there always enough
payload register to accomodate this. But the following change is going
to make the inline parameter register optional.
Since SHADER_OPCODE_MEMORY_FENCE is emitted in the generator as SIMD1
NoMask (see brw_memory_fence), we can limit ourselves to SIMD1
exec_all() in the IR as well so that the IR accounts for grf0 as a
source.
