zink: remove needless requirements

zink: remove needless requirements

We never required the uniform texel buffer bit for more than
bufferFeatures for a bunch of these formats.

Similarly, we *don't* need the uniform texel buffer bit for sampled
image access.

For the image-dimensions, the Mesa frontend doesn't validate the max 1D,
3D or Cube sizes, nor the max texture layers. So we'll expose GL 4.1
without these, even if that's not conformant.

Finally, we don't require robustImageAccess2 for OpenGL 4.3 at all. All
we need is the robustBufferAccess feature.
