Issue Description:

According to the proposal, https://github.com/apple/swift-evolution/blob/main/proposals/0335-existential-any.md#metatypes:

P.Protocol, becomes (any P).Type

also,

The protocol metatypes for Any and AnyObject are spelled (any Any).Type and (any AnyObject).Type, respectively.

However, the following code shows the two are not the same considering Any:

Int.self is Any.Protocol // false
Int.self is (any Any).Type // true <- how come?
protocol P {}
P.self is Any.Protocol // false
P.self is (any Any).Type // true <- how come?

It seems, (any Any).Type is transformed into Any.Type by the compiler.

Also, it is illegal to write something like

let something = (any Any).Type.self // error: expected ',' separator.

A same problem exists for AnyObject.

(any AnyObject).Type.self == AnyObject.Protocol.self // false <- how come?
(any AnyObject).Type.self == AnyObject.Type.self // true <- how come?
