Basic vertex/fragment shader I/O and sysval allocation rewritten to use the new compiler/driver interface, with allocation moved entirely into the driver. RHW coeffs now only emitted when required. Boilerplate support for converting formats for vs inputs/fs outputs. Signed-off-by: Simon Perretta <simon.perretta@imgtec.com> Acked-by: Frank Binns <frank.binns@imgtec.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/32258>
