`[.]Type` completion for `(any P).` shows it will produce an existential metatype

[AnthonyLatsis]

Test case:

// RUN: %empty-directory(%t)
// RUN: %target-swift-ide-test -batch-code-completion -source-filename %s -filecheck %raw-FileCheck -completion-output-dir %t
protocol P {}

(any P).#^COMPLETE?check=META^# 
// META: Keyword/CurrNominal:  Type[#(any P).Type#]; name=Type

This test will fail, because the current completion is Type[#any P.Type#]; name=Type. Notice how it thinks the completion will produce an existential metatype any P.Type, whereas the actual result is the singleton metatype (any P).Type.

Note
any syntax was proposed in SE-0335.

Environment

• Swift 5.9-dev (c1d5118)

@Rajveer100 This one is somewhat less involved if you’re interested.

[Rajveer100]

So do you suggest working on this, before #65699?

[AnthonyLatsis]

Yeah, I think that’s a good idea if this is your first time working on code completion.

@AnthonyLatsis What could be the cause for this?
