In preparation to the changes that would allow to not need them.
It is worth to note that it is likely (we have some ideas in mind)
that we would need to bring back pre-generate variants on the
future. The approach is slightly different on v3dv_pipeline vs
v3dv_cmd_buffer:
* v3dv_pipeline: even after the clean-up, we had code for all the
functions they have, even if they were doing less things
(specifically, a second shader variant), so they still make sense
on their own, and serve as template for adding support of multiple
pre-generated shader variants in the future.
* v3dv_cmd_buffer: as we really don't need to fill up the key with
some after-pipeline data, we would end with some functions empty
(specifically cmd_buffer_populate_v3d_key). Even as a placeholder,
that would be odd. Additionally the current code has a lot of
boilerplate code (functions to fill up vs, cs and fs keys are
basically the same), and we already have in mind refactor them. So
it would be better to remove all of them, instead of keeping
around some code we would not be happy with. If in the future we
pregenerate more that one variant, hopefully the new code to chose
between them would be better.
