Manual cherry-pick of https://dawn-review.googlesource.com/c/tint/+/71681

Original commit message (modified):

resolver: Fixes for bitcasts

Add missing validation for bitcasts. We were permitting any bitcast that wasn't a being cast to a pointer type, when the spec only allows:
 * numeric_scalar to numeric_scalar
 * vecN<numeric_scalar> to vecN<numeric_scalar>

Add lots of tests.
