etnaviv: Add support for ARB_vertex_type_2_10_10_10_rev

Browse Source 
This extension seems to be supported on GC3000 (HALTI2) and later hardware.
While no explicit feature bit documents this capability, testing
confirms that the required vertex formats work correctly on these GPUs.

This patch adds the missing B10G10R10A2 vertex format variants
(UNORM, SNORM, USCALED, SSCALED), gates support behind the HALTI2
feature check, and updates features.txt to reflect the new capability.

All relevant piglit tests pass.
