JS/TS package acquisition (#184438)

* Experiment with adding ata using `@types` packages shipped in an extension

* Use own file system instead of `https`

* JS/TS type support on web

* Tsconfig needs esModuleInterop not module:nodenext

We actually want webpack to emit commonjs, but need to write ES default
imports to use node-maintainer

* fix package.json indentation

* Adding setting to disable web type acquisition

* Fix merge of yarn lock

* Fixing merge errors

* Fixing errors

* Pick up package externally

* Fixing conflicts

* Bump version
