nir: Add nir_lower_viewport_transform
On Mali hardware (supported by Panfrost and Lima), the fixed-function
transformation from world-space to screen-space coordinates is done in
the vertex shader prior to writing out the gl_Position varying, rather
than in dedicated hardware. This commit adds a shared NIR pass for
implementing coordinate transformation and lowering gl_Position writes
into screen-space gl_Position writes.
v2: Run directly on derefs before io/vars are lowered to cleanup the
code substantially. Thank you to Qiang for this suggestion!
v3: Bikeshed continues.
v4: Add to Makefile.sources (per Jason's comment). Bikeshed comment.
Ian and Qiang's reviews are from v3, but no real functional changes from
v4. Rob's review is from v4.
