Updated: Only auto-import from package.json (#32517)
* Move package.json related utils to utilities

* Add failing test

* Make first test pass

* Don’t filter when there’s no package.json, fix scoped package imports

* Use type acquisition as a heuristic for whether a JS project is using node core

* Make same fix in getCompletionDetails

* Fix re-exporting

* Change JS node core module heuristic to same-file utilization

* Remove unused method

* Remove other unused method

* Remove unused triple-slash ref

* Update comment

* Refactor findAlias to forEachAlias to reduce iterations

* Really fix re-exporting

* Use getModuleSpecifier instead of custom hack

* Fix offering auto imports to paths within node modules

* Rename things and make comments better

* Add another reexport test

* Inline `symbolHasBeenSeen`

* Simplify forEachAlias to findAlias

* Add note that symbols is mutated

* Symbol order doesn’t matter here

* Style nits

* Add test with nested package.jsons

* Fix and add tests for export * re-exports

* Don’t fail when alias isn’t found

* Make some easy optimizations

* Clean up memoization when done

* Remove unnecessary semicolon

* Make getSymbolsFromOtherSourceFileExports pure

* Cache auto imports

* Revert "Cache auto imports"

This reverts commit 8ea4829587.
