Charlie Marsh b3fb864847 [ty] Show a diagnostic for unsupported inferred Python version (#24581) ...

## Summary

This PR adds the infrastructure to surface diagnostics during project
and program settings resolution. The motivating use-case is: when we see
an unsupported Python version in an editor, we want to surface a
diagnostic rather than limiting to a `tracing` warning, as in:

```
warning[unsupported-python-version]: Ignoring unsupported inferred Python version `3.16`; ty will use Python 3.14 instead.
 --> venv/pyvenv.cfg:2:16
  |
2 | version_info = 3.16.0
  |                ^^^^^^
3 | home = base/bin
  |
info: Expected one of `3.7`, `3.8`, `3.9`, `3.10`, `3.11`, `3.12`, `3.13`, `3.14`, `3.15`.
info: Set `python-version` explicitly to override the inferred version.
info: The version was inferred from your virtual environment metadata.
```
