For #271167
This makes it so our built-in extensions can mostly be built using `tsc` on the command line. Previously the extensions were picking up a lot of typing info from the root `node_modules` that meant they weren't truly independent
**Bug**
Most VSCode extensions currently specify `"exclude"` in their `tsconfig.json` but not `"include"`. This may result in extra files being included in each project
**Fix**
Add `"include": ["src/**/*"]` to all extension tsconfig files
* Remove unneeded d.ts files from extensions
Moves most extensions to use the lib files for the standard library that typescript provides.
* Remove a few more node.d.ts references
