imgtool: Add 'dumpinfo' command
Add new 'dumpinfo' command that can parse a signed image and
print all the available information from the header, TLV area and
trailer in the form of a basic "image map".
The --outfile option can be used to write the image information
to an output file in serialised YAML format.
