* allow file level `union {}` to parse as tuple field
this was found while fuzzing zls.
* before this patch the input `union {}` crashed the parser. after
this, it parses correctly just like `struct {}`.
* adds behavior tests for both inputs `struct {}` and `union {}`,
checking that each becomes a file level tuple field.
