6e736c120e Added custom error message when trying to assign constraint type to generic type parameter (#30394) 
* Added custom error message when trying to assign constraint type to generic type parameter

Fixes #29049.

This also adds the new message in chained error messages. `typeParameterDiamond4.errors.txt` shows it appearing twice in the "diamond" scenario. I can't tell if this severely increased amount of nested messages is good or bad...?

* Updated diagnostic message per suggestion

* Align formatting with local custom

d865ea774a resolveName: remove useless case (#28669) 
PropertySignature cannot occur in a class.
The condition inside the clause required the parent to be a class, so it was never true.

This removes the case clause and the part of the condition that is now useless.

6487d1ffe0 Remove the rule that replaces a union of literal types with the base type when comparing equality to a type that isn't a union of literal types. (#27588) 
type when comparing equality to a type that isn't a union of literal
types.

The rule is redundant because a primitive type is already directed-
comparable to a value of that primitive type, and it causes errors to be
missed when comparing a type parameter _constrained_ by a union of
literal types to another union of literal types.

The baseline changes look like improvements to me.

Fixes #26758.
