shader_checker: Add typechecker support for extra array level

In the VS->GS, VS->TCS, or TES->GS interfaces, the consuming side of the
interface is arrays of the producer's interface, as we're dealing with
an array of vertices. This requires a bit more care in the typechecker:

- Walking from the complete type down, the first time we see an array,
  it's the array-of-verts case; strip it off and compare the LHS to the
  element type.
- If we see a leaf type without encountering the array type node, then
  we mismatch. For the purposes of this check, structs are treated as
  leaves.

V2: Simplify slightly.
