binman: Support adding files
In some cases it is useful to add a group of files to the image and be
able to access them at run-time. Of course it is possible to generate
the binman config file with a set of blobs each with a filename. But for
convenience, add an entry type which can do this.
Add required support (for adding nodes and string properties) into the
state module.
