mesa: add NV_image_formats extension support
This extension can be enabled automatically as it is a subset of
ARB_shader_image_load_store.
v2: Replace helper function by qualifier struct field (Ilia)
Enable NV_image_formats using ARB_shader_image_load_store (Ilia)
v3: Drop extension field from gl_extensions (Ilia)
