Adds a unit test, and some smaller edits:
- Remove the `=` when defining names, in order to change `}` placement
by clang-format on uses.
- context:
https://github.com/carbon-language/carbon-lang/pull/6053#discussion_r2343423178
- I believe with `EnumBase` that keeping the `=` had been a deliberate
choice, so this PR is intended to confirm that removing it is okay.
- Delete `EnumMaskBase::name`
- context:
https://github.com/carbon-language/carbon-lang/pull/6053#discussion_r2344233707
- We can't just do nothing because `EnumBase::name` uses indexing that's
incompatible with `EnumMaskBase`.
- Some small comment cleanups.
- Tests don't need to be in the `Carbon` namespace anymore, macros work
fine in other namespaces, but it's still the right namespace.
- Documentation on `EnumBase::name` seems to be referring to a prior
structure, wherein we had a macro defining the function instead of the
`Names` array.

Continuing with #3070. Just a dir and file rename (only prefix change is
lexer_file_test). Everything in the lex dir should be marked as a move.
Note, I think this closes#3070. There may still be further cleanup
later, but the organizational changes suggested there are being
completed.
