Fixed a bug whereby an explicit TypeAlias definition that includes a generic type with no explicit type arguments was not assuming Unknown for those type arguments. For example, A: TypeAlias = list should assume that A is equivalent to list[Unknown].
...
Added a missing diagnostic for an attempt to specialize a class that has already been specialized. This can occur in the case of a type alias, such as `A = list[int], A[int]`.
