med1844 0ec2ad2fa5 [ty] Emit error for invalid binary operations in type expressions (#18991) ...

## Summary

This PR adds diagnostic for invalid binary operators in type
expressions. It should close https://github.com/astral-sh/ty/issues/706
if merged.

Please feel free to suggest better wordings for the diagnostic message.

## Test Plan

I modified `mdtest/annotations/invalid.md` and added a test for each
binary operator, and fixed tests that was broken by the new diagnostic.
