Paolo Tranquilli 874fe2b8f9 Swift: introduce an in-memory file hash cache
File hashing is now done internally in `SwiftFileInterception` (and
exported as a `getHashOfRealFile` function for future use in linkage
awareness), and using a per-process in-memory cache. The persistent
caching of paths is removed, so the solution is now robust against input
file changes during the build.

For the same reason, the hash to artifact mapping have the symlinks
reversed now. The artifacts themselves are stored using the hash as
filenames, and the original paths of the artifacts are reacreated in the
scratch dir with symlinks mostly for debugging purposes (to understand
what artifact each hash corresponds to, and to follow what was built by
the extractor).
