yocto-bsp: Add a processing pass to get rid of 'strange' filenames

Operating systems that can't handle filenames containing anything but
uppercase letters don't like to see 'strange' characters in filenames
such as the file and directory names yocto-bsp uses as part of its
templating mechanism.  To fix this, we essentially add another level
of metadata into the template files themselves rather than into their
names, and add a processing pass that internally gives us what we had
before.  Specifically:

  - strange characters in filenames are moved inside the files they
    apply to, to the first line of the file prepended with '#
    yocto-bsp-filename {{...}} filename | this'

  - strange characters in directory names are moved inside a new file
    of the same name but ending in .noinstall and with the first (and
    only) line of the file prepended with '# yocto-bsp-dirname {{...}}
    dirname'

If the new filename contained in the yocto-bsp-* tag is 'this', the
filename is the existing name of the file.  For a dirname, this would
be the filename with .noinstall removed.

"Fixes" [YOCTO #5312].
