Unless we are combining multiple workgroups in the same HW thread,
there's no advantage of using SIMD16 when SIMD8 already fits the
entire workgroup.

Variable workgroup size works by compiling as much SIMD variants as
possible and then selecting the right one during dispatch (when the
actual workgroup size is passed to us).
Instead of replicating the logic in a separate function, reuse the
same logic for regular SIMD selection. And move function for that
together with the remaining simd selection functions.

Clean up the logic and move it to functions that work with prog_data
attributes to select the right SIMD. This shouldn't change any
behavior compared to the original.
Having it extracted will allow reuse by Task/Mesh and make it easier
to write tests.
