Documentation symbols not added to exported types in declaration files if they are referenced in a declared global

[JohnnyMorganz]

For a definition file like so:

declare class Foo
    function bar(self, x: string): number
    function bar(self, x: number): string
end

a documentationSymbol is correctly attached to Foo as @test/globaltype/Foo

However, if I then make the file like the following

declare class Foo
    function bar(self, x: string): number
    function bar(self, x: number): string
end
declare function newFoo(): Foo

Foo no longer gets any documentation symbols attached to itself or its props

Taking a deeper look, it seems to be related to the code at https://github.com/Roblox/luau/blob/54324867df2d91bc527f6de9217b05c3a9ae235f/Analysis/src/Frontend.cpp#L163-L181 and generateDocumentationSymbols
The generate doc symbols function doesn't add symbols if the type is persistent

It seems that, in the first example, the cloned ty is not persistent and so doc symbols get generated for it, but because i've added the declare function newFoo() in the second example, the cloned ty is already persistent, so it fails to add a doc symbol

Looks like a pass to make types persistent should run separately after everything is cloned and annotated.

Should get fixed later this week.
