[VFS] Add getter for mapping entries.

When generating a reproducer in LLDB we build up the mapping but don't
immediately copy over the files on the file system.

Rather than keeping a separate data structure with real and virtual
paths, we might as well reuse the entries already stored in the
YAMLVFSWriter to lazily copy over the files when needed.
