Display all symbol meanings in quick info

[ahejlsberg]

With this PR we display all meanings of a symbol in Quick Info. An (alias) prefix is displayed for non-local meanings that arise from import and export aliases.

Pull request overview

This PR enhances hover/quick info functionality to display all meanings (value, type, and namespace) of a symbol, with proper handling of import and export aliases. The (alias) prefix is displayed for non-local meanings that arise from imports and exports.

Key changes:

• Refactored symbol display logic to recursively show all meanings of aliased symbols
• Added proper nil checking for symbols before processing
• Removed unused inConstructorContext function

This fixes a massive number of fourslash tests that just need to be regenerated; unfortunately you'll probably need to do the goofy manual fix for getOccurrencesIfElseBroken if that isn't fixed by a plain npm run updatefailing.

I haven't had time to go rewrite these scripts to fix this yet (sorry...)

[jakebailey]

Hm, it maybe it doesn't fix a bunch of tests. It seems like it's actually breaking something to do with the test fix detection. I am now looking into this.

[jakebailey]

Ah, the fourslash code is breaking because TestAliasMergingWithNamespace when unskipped causes a stack overflow. Probably should fix that lest a user hit it.
