Description
Stumbled across this issue where when a ray query is used in an alias spirv-out crashes naga. This is because it only searches for ray queries without names. Instead, use a local type to be written out.

Testing
Adds snapshot test which failed before but now works.

Squash or Rebase?
One commit, so probably doesn't matter.

Checklist

• Run cargo fmt.
• Run cargo clippy --tests.
