Use TS InferredProject, ConfiguredProject instead of language service API

[johnsoncodehk]

If project depend on some large packages (lot of .d.ts files), language service API spend lot of time to resolve auto import from node_modules packages.

TS implement cache logic in InferredProject, ConfiguredProject over language service API to avoid performance issue. Not sure is possible to use InferredProject, ConfiguredProject instead of language service API in volar. If can, should be able to fully achieve vanilla TS level performance.

In 0.30.0, you can config "typescript.suggest.autoImports": false to skip calculate auto import for now.

@johnsoncodehk In the Settings. The json?

@jahnli in VSCode settings / .vscode/settings.json.

Is that right ?

Just tried reference TS internal code to implement auto-import cache logic for language service API, but it may invalid at any time with TS version update, has happened once in the past (15e744f).

And please note that I haven't implemented file watcher for this, when node_modules / package.json updated, you need to restart volar server to refresh auto-import cache for now.
