OvmfPkg/VirtioFsDxe: split canon. path into last parent + last component
Given a canonical pathname (as defined by VirtioFsAppendPath()), different
from "/", introduce a helper function for:
- looking up the NodeId of the most specific parent directory, and
- exposing the last component stand-alone (which is therefore a direct
child of said parent directory).
This splitting operation will be necessary in multiple subsequent patches.
