This PR implements the interface expected by the frontend, as built by @nkcsgexi in:
swiftlang/swift#32355
swiftlang/swift#32450

Swift module's explicit Swift module dependencies are now encoded in a JSON file, passed with -explicit-swift-module-map-file. The key benefit is that now the frontend doesn't need to deserialize the .swiftmodule file just to collect the module's name.

We shouldn't need the CodingKeys if we use these keys as the field names.

I mostly just wanted to stick to the Swift naming convention (Types start with an uppercase letter, variables start with a lowercase latter), but I don't have a strong preference.

That's fair. How about we change the compiler-side to use keys conforming to the Swift naming convention and remove CodingKeys?

@nkcsgexi , I've addressed the comments, but the change now has to wait for swiftlang/swift#32507 to be picked up by the next master snapshot toolchain.

We haven't had a new snapshot toolchain on swift.org for a few days now, and this change has a dependency on one of Xi's changes that was made after the most recent one one was created. So this will need to wait a little bit until it can be tested in the CI.
