[omnibox] Leverage the existing file URL parsing routine

A new file URL parsing routine was added in a previous CL (1025953)
for detecting hash/pound refs in file URLs. This made file: schemes
a bit of an exception. This CL removes that routine and leverages
the existing routine, calling it from where the other URL types
are parsed, treating file: schemes like the other schemes.
