mesa: Strip arrayness from interface block names in some IO validation

mesa: Strip arrayness from interface block names in some IO validation

Outputs from the vertex shader need to be able to match
per-vertex-arrayed inputs of later stages.  Acomplish this by stripping
one level of arrayness from the names and types of outputs going to a
per-vertex-arrayed stage.

v2: Add missing checks for TESS_EVAL->GEOMETRY.  Noticed by Timothy
Arceri.

v3: Use a slightly simpler stage check suggested by Ilia.
