Jim Blandy 509ea4c857 [wgsl-in] Generate no code for trivial vector/matrix construction. (#2576) ...

Do not emit an `Expression::As` conversion for WGSL like `vec3(v)`
where `v` is already a `vec3`, or `mat2x3(m)` where `m` is already a
2x3 matrix. This doesn't fix any bugs, but it makes it clearer to the
reader of `Lowerer::construct` that no conversion can actually take
place in this case.

Some snapshots are affected because `As` expressions whose `width` is
`None` are bitcast expressions, which the constant evaluator does not
yet support. When this commit removes those `As` expressions, the
constant evaluator can reduce the expression to a `Literal` or
`ZeroValue`, which is then concealed by #2539.
