Error on mapped type w/properties (#46346)
* Error on mapped types with properties

1. Error on properties of type literals with computed properties whose name is a
binary expression with `in`, because that's a good sign of a mapped
type.
2. Parse following properties on mapped types, and error on them.
3. Stop checking computed property names in (1) to avoid producing
errors based on misinterpreting mapped type syntax as an expression.

* add comment in types.ts

* Update API again

* Check interfaces and classes too

* Add missed check in updateMappedTypeNode

Track source and target relationship stack depth seperately, only increase on change in value (#41821)
* Track source and target relationship stack depth seperately, only increase on change in value

* Add baselines for test from #43485

* Bail on unwrapping conditional constraints on the source side when the source conditional is already known to be spooling out of control

* More usage of isDeeplyNestedType to block _specifically_ conditional recursion on only one side

* Negative cases of getNarrowedType that match the exact type should be filtered out, even when generic

* Add test and fix for #44404

* Swap to manually specifying left and right recursion

* Rename Left -> Source, Right -> Target
