Handle DefinitelyTyped typings in our custom typescript configuration

[jacobtylerwalls]

In 7.6, we were unable to find a solution for installing types from DefinitelyTyped. You're supposed to be able to just npm --save-dev @types/somepackage, but our custom node_modules munging for arches applications is adding complexity.

Opening a follow-up ticket to capture the enhancement request.

Just circling back on this @jacobtylerwalls . Dove into the workspaces solution and I couldn't get it work for me; I don't believe it works for sibling projects. Symlinking in production is a no-go as well. I had some moderate success with messing around with the noEmit and emitDeclarationsOnly and compile flags, but nothing worth merging in at the moment.
