[clang] NFC: new tests and some cleanups on existing ones (#142293)

Browse Source 
This offloads some test changes from another PR in order to facilitate
review.

- Adds some new tests.
- Cleans stray spaces and newlines on existing tests.
- Regenerates some AST json dumps, as the generator now includes
offsets.
