other caps are fine-grained and single-purpose, this cap encode several
features in one. And since OpenGL cares more about single features, it'd
be nice to get rid of this one.

As it turns, this is now relatively simple. We only really care about
three features using this cap, and those already got their own caps. So
we can remove it, and make sure all current drivers just give the same
response to all of them.

The only place we *really* care about SM3 is in nine, and there we can
instead just re-construct the information based on the finer-grained
caps. This avoids DX9 semantics from needlessly leaking into all of the
drivers, most of who doesn't care a whole lot about DX9 specifically.

Theoretically, any format we can texture from we can also render to. In
practice, there are a few corner cases that we need to disable
explicitly.

For one, we do have to restrict SCANOUT formats to workaround
buggy apps (in particular, dEQP which with --deqp-surface-type=window
under Weston will end up with RGB10_A2 and complain about low alpha

- vk_icdGetInstanceProcAddr
- vk_icdNegotiateLoaderICDInterfaceVersion

and this one is optional:
- vk_icdGetPhysicalDeviceProcAddr
