Dhruv Manilawala b09e5f40df Remove Expr::Invalid (#10386) ...

## Summary

This PR removes the `Expr::Invalid` variant from the AST. Instead, we'll
try to retain as much valid information as possible and use an empty
`Expr::Name` with `ExprContext::Invalid` as a replacement.

## Test Plan

- [x] All tests pass
- [x] No performance regression
