Commit message:
spec: remove restriction on channel element types for close built-in (bug fix)
The spec states that if the argument type for close is a type parameter,
it's type set must only contain channels and they must all have the same
element type. This latter requirement (all must have the same element
type) was never enforced by the compiler, nor is it important for
correctness or required by the implementation.
This change removes this requirement also in the spec and thus
documents what was always (since 1.18) the case.
Fixes #74034.
