forwprop: Fix ICE when building a VEC_PERM_EXPR [PR94683]
The type compatibility handling in simplify_vector_constructor is
based on the number of elements and on element type compatibility,
but that's no longer enough to ensure that two vector types are
compatible. This patch uses a VIEW_CONVERT_EXPR if the permutation
type and result type are distinct.

VIEW_CONVERT_EXPR to handle mixtures of similarly-structured
but distinct vector types.
