Add tooling for building tsconfig-all.json references list dynamically

Description of issue

The list of references in tsconfig.all.json is quite long, let's build it dynamically.

Requirements:

• building on the fly likely adds back some (or all) of the perf benefit at CI time seen in One config #2160 so take a look at compile and commit approaches instead
• dynamically finding all included configs might be difficult so include a manual escape hatch. this could just be "add it after it's build" but it would be great if the escape was in the generator so that we don't need to do anything manually on a regular basis
