swr: mark color clamping as unsupported

There is no functionality in swr to clamp either vertex or frag colors.
This could be added in swr_shader, at which point these could be
re-enabled.

swr: make sure that all rendering is finished on shader destroy

Rendering could still be ongoing (or have yet to start) when the shader
is deleted. There's no refcounting on the shader text, so insert a
pipeline stall unconditionally when this happens.

[Note, we should instead introduce a way to attach work to
fences, so that the freeing can be done in the current fence.]

swr: mark rgb9_e5 as unrenderable

The support in swr requires shaders to output the components as UINTs.
This is not how GL or Gallium work, and since this is not a
required-renderable format, just leave it out.
