Description

Typing $foo in a Svelte file where foo is defined in some other file and not imported yet results in no auto import completion currently. It would be great if it would.

Proposed solution

The idea would be to do a hidden global autocompletion at the start of the file and filter for the given name just without the $ prefix. To not tank performance, those autocompletions should be cached. The idea could be to trigger them on $ and save them for a minimum of 10 seconds or as long as no modification to another Svelte file's module context or another TS/JS file was made.

(Completions are already triggered currently when typing $foo but they don't contain foo as a suggestion due to the leading dollar sign)
