Inlay hints for compilation conditions

[MahdiBM]

Is your feature request related to a problem? Please describe.
Add a setting to show inlay hints at the end of compilation conditions.
Basically like Xcode has recently added.

Apparently Xcode tries to be smart and doesn't show the hint in certain situations if it thinks it would be obvious, but I kind of like the behavior to be consistent and show it at all times.

I'd also like to have a button or something to be able to jump to the definition site. Maybe also the text should mention the line number of the definition site, or maybe a visual way to indicate from start to end of a compilation condition code branch.

We also need to consider what would be shown for #else branches ... Xcode simply shows nothing.

VSCode:

Xcode:

Xcode wouldn't show the inlay hint if the situation was exactly the same as the VSCode image, meaning when the whole condition contained only 2 lines.

Describe alternatives you've considered
Manually using comments at the end of each condition.

SourceKit would need to do this

I guess it would be implemented as a code action
