Sema: Allow T == NonCopyableOrEscapable same-type constraints without a redundant T: ~Copyable.
...
Enhance the logic in `applyInverses` to also take into account same-type constraints spelled in
the generic signature, so that same-type-constraining a type parameter to a type that is itself
not `Copyable` or `Escapable` suppresses the default application of those constraints on the
type parameter. Fixes rdar://147757973.

RequirementMachine: Skip protocol type aliases that contain unbound dependent member types
...
In the below, 'Self.A.A' is not a type parameter; rather, since
'Self.A' is concretely known to be 'S', we resolve it as 'S.A',
which performs a name lookup and finds the concrete type alias 'A':
public struct S {
public typealias A = Int
}
public protocol P {
typealias A = S
}
public struct G<T> {}
public protocol Q: P {
typealias B = G<Self.A.A>
}
This is fine, but such a type alias should not participate in
the rewrite system. Let's exclude them like any other invalid
requirement.
The type alias itself is not an error; however, it is an error
to use it from a 'where' clause requirement. This is not
diagnosed yet, though.
Fixes rdar://136686001.

Require explicit statement of all Copyable/Escapable requirements for conditional Copyable/Escapable conformances.
...
As specified by the SE-0446 acceptance, extensions that declare a type's
conditional `Copyable` or `Escapable` ability must reiterate explicitly all
of the `Copyable` and/or `Escapable` requirements, whether required or not
required (by e.g. `~Copyable`) that were suppressed in the original
type declaration.
