fix(mfe): factor in configs to hashes

[chris-olszewski]

Description

Start factoring in any MFE configs found into task hashes so changes to the config will invalidate any applications that are a part of a MFE setup.

⚠️ We achieve this by adding this to the global cache. This is sub-optimal as it means tasks unrelated to MFEs get invalidated, but we make this temporary trade off in favor of correctness. See TODO for the planned path forward.

Testing Instructions

Added unit tests, verified that changing a MFE config file will now invalidates all MFE apps:

Looks good, there may be even more changes here so this is a good approach to unblock for now.
