Improved startup responsiveness on large monorepos by making source file discovery code non-blocking. This addresses #3075.

Without this change, pyright hangs for tens of seconds when used on a large monorepo (>100K files). With this change, pyright's LSP functionality (hover, goto definition, etc.) are responsive almost immediately. Some LSP functions like "find all references" or "workspace symbols" will be inaccurate or incomplete until all project files are enumerated, but these features are not all that usable on a monorepo — at least unless you're using pylance with a populated index.

…ile discovery code non-blocking. This addresses #3075.

@rchiodo, I'd appreciate a code review for this change. I want to make sure that it doesn't break any pylance functionality.

Okay thanks. I'll have to pull it into pylance to try it out. I don't think I can really tell just by looking at it.

// Given a file map returned by the source enumerator, this function
// adds any open files that match the include file spec and returns a
// final deduped file list.

i wonder if we should change this to return an iterator instead.. for cases where its 100k plus entries.

I think this may mess up pylance's tracking of the file list. We don't schedule analysis in pull diagnostics mode. Instead diagnostics are requested by the client. So this function doesn't run.

That would mean the tracking list would be off. We'd have to do this tracking update in that scenario too.

Can you move this code to a separate function? We can then call it for pull diagnostics in Pylance.

I've refactored the code and moved this portion to a new protected method that pylance can call in the pull diagnostics mode.

Otherwise I tested it with Pylance and it sure seems like things are faster.
