Add `EXTRA-ARGS:` support to file_test, to add arguments without overriding the default arguments. Use `EXTRA-ARGS: --no-dump-sem-ir` to turn off SemIR dumping and thus SemIR testing in the int builtin tests, which validate correct behavior through diagnostics instead. This doesn't get us any closer to supporting more targeted SemIR dumping / testing, but this seems to be a generally useful feature anyway. Most existing tests using `ARGS` have been switched over to using `EXTRA-ARGS`. Requested in review of #4716.
