[vk] disable VK_EXT_vertex_input_dynamic_state again (#2954)

Browse Source 
DO NOT REMOVE THIS! EVER! EVEN IF MESA CLAIMS TO FIX IT!

A few months ago, Aleksandr and I did extensive testing on a 6600 and
6950XT and were able to confirm that VK_EXT_vertex_input_dynamic_state
is indeed broken beyond repair on RADV. MESA has claimed multiple times
to fix this, yet it's never budged once (average GitLab users)

Most games literally do not work without this. DO. NOT. REMOVE.
EVER!
