Robert Griesemer dab16c1c90 cmd/compile/internal/types2: accept constraint literals with elided interfaces 
When collecting type parameters, wrap constraint literals of the
form ~T or A|B into interfaces so the type checker doesn't have
to deal with these type set expressions syntactically anywhere
else but in interfaces (i.e., union types continue to appear
only as embedded elements in interfaces).

Since a type constraint doesn't need to be an interface anymore,
we can remove the respective restriction. Instead, when accessing
the constraint interface via TypeParam.iface, wrap non-interface
constraints at that point and update the constraint so it happens
only once. By computing the types sets of all type parameters at
before the end of type-checking, we ensure that type constraints
are in their final form when accessed through the API.

For #48424.
