Eagerly resolve module specifiers for auto-import completions in --moduleResolution node12+ (#48752)

* Add failing test

* Block auto-import module specifiers including node_modules path

* Eagerly resolve module specifiers in completions in nodenext so failures can be filtered

* Add completion info flags for telemetry

* Update API baseline

* Update completions baselines

* Fix missed boolean flip

* Fix remaining tests
