[ty] use interior mutability in type visitors (#19871) 
## Summary

Type visitors are conceptually immutable, they just internally track the
types they've seen (and some maintain a cache of results.) Passing
around mutable visitors everywhere can get us into borrow-checker
trouble in some cases, where we need to recursively pass along the
visitor inside more than one closure with non-disjoint lifetime.

Use interior mutability (via `RefCell` and `Cell`) inside the visitors
instead, to allow us to pass around shared references.

## Test Plan

Existing tests.
