Validate SPIRV produced by Tint

The now-removed SPIRV-Cross path used to always do this, and the
pure Tint-only path never actually validated the SPIRV. Tint
does not run SPIRV-Tools validation on its output, so add in
validation to ensure we don't pass invalid SPIRV to the driver.
The validation can probably eventually be removed when we're more
confident that Tint's SPIRV output is always correct.

Also include various cleanups for old / unused code.
