vulkan: optimize vk_dynamic_graphics_state_any_dirty

Browse source 
For drivers using the new state tracking, __bitset_test_range can be
surprisingly hot because we have a lot of dirty bits and __bitset_test_range has
to handle lots of special cases. __bitset_is_empty does not have to worry about
those special cases so can be much faster.
