Add support for jsconfig.json resolution (#3409)

There doesn't appear to be any issues with just returning a `jsconfig.json` when we're looking for a `tsconfig.json` (provided one didn't exist). Finding this gives a `TsConfigReferenceVc` (used for finding type definitions only) and enables the `paths`/`baseUrl` resolution options.

Fixes WEB-230
