panvk: Fix regressions caused by the per-gen XML transition
The panvk_entrypoints.h header is included by all panvk_vX_xxx.c source files, without this dependency the build can fail.
This should fix #5295 (closed).
Patch 2 is fixing a regression caused by the per-gen XML transition on Midgard GPUs.
