radv/entrypoints: Only generate entrypoints for supported features
This changes the way radv_entrypoints_gen.py works from generating a table containing every single entrypoint in the XML to just the ones that we actually need. There's no reason for us to burn entrypoint table space on a bunch of NV extensions we never plan to implement. RADV implements VK_AMD_draw_indirect_count, so add that to the list.
