internal/lsp/source: add a FileSource interface

Rename Snapshot.GetFile to GetVersionedFile, and make the signature of
GetFile consistent with the corresponding method on session and cache.
This allows algorithms that depend only on file state to be expressed
using this API. In a subsequent CL, this is used for building and
testing the workspace module.

Preeemptively add the FileSource interface for use in these algorithms.
