Add some raster pipeline perspective asserts

I meant to add these when removing the guard, but since we landed without
a guard, might as well do it now.

A couple of things exposed by these asserts:

1) we need to also catch perspective in local matrices

2) we need to disallow burst mode with perspective

Also tweak the predicate to hasPerspective() instead of explicit mask
check.
