Teach find_(path|file) about Linux multiarch (#13742)

Implement support for multiarch include directories as specified here:

  https://wiki.ubuntu.com/MultiarchCross

Generalize the multiarch feature added in commit b41ad3b3 (Teach
find_(library|package) about Linux multiarch, 2011-06-08) to the
find_path and find_file commands.  Teach them to search
<prefix>/include/<arch> whenever they would search <prefix>/include.
