What does this MR do and why?
anv: update shader descriptor resource limits
Some limits got stuck to the old binding table limits. Those don't

Fixes: 6e230d7607 ("anv: Implement VK_EXT_descriptor_indexing")
Fixes: 96c33fb027 ("anv: enable direct descriptors on platforms with extended bindless offset")
