Add per-file-target-version option (#16257)

## Summary

This PR is another step in preparing to detect syntax errors in the
parser. It introduces the new `per-file-target-version` top-level
configuration option, which holds a mapping of compiled glob patterns to
Python versions. I intend to use the
`LinterSettings::resolve_target_version` method here to pass to the
parser:

## Test Plan

I added two new CLI tests to show that the `per-file-target-version` is
respected in both the formatter and the linter.
