freedreno/ir3: add is_tex_or_prefetch()
Some of the aspects of tex prefetch are in common with normal tex
instructions, such as having a wrmask to control which components
are written. Add a helper for this.
This should result in actually using the prefetch wrmask to avoid
fetching unneeded components.
