Allow passing ParseOptions to inline tests (#16357)

## Summary

This PR adds support for a pragma-style header for inline parser tests
containing JSON-serialized `ParseOptions`. For example,

```python
# parse_options: { "target-version": "3.9" }
match 2:
    case 1:
        pass
```

The line must start with `# parse_options: ` and then the rest of the
(trimmed) line is deserialized into `ParseOptions` used for parsing the
the test.

## Test Plan

Existing inline tests, plus two new inline tests for
`match-before-py310`.
