v3d: flag dirty state when binding new sampler states

We emit code to saturate texture coordinates when using clamp wrapping
mode so if we don't flag the dirty state here we don't get to recompile
the shaders when the wrapping mode changes.

v2:
  - Do the same when setting sampler views (Eric)
  - Use a switch statement instead of an if ladder.
  - Swap the shader stage assertion with an unreachable.
