file: Add COPY/INSTALL option for fixed layout relative to a directory

Add a `FILES_FROM_DIR` option to install a specific set of files
specified relative to a given directory and preserve their layout
in the destination.  Currently we intend to use this internally
to implement other things so we don't provide an `install()`
porcelain or documentation yet.
