fmaptool: Introduce the fmd ("flashmap descriptor") language and compiler
This adds a compiler for a language whose textual representation of flashmap regions will be used to describe the layout of flash chips that contain more than just a single CBFS. Direct integration with cbfstool (via a new command-line switch for the create action) is forthcoming but will be added separately. BUG=chromium:461875 TEST=Use Chromium OS's cros_bundle_firmware script on the fmap.dts file for panther. Using the latter file as a reference, write a corresponding fmap.fmd file and feed it through fmaptool. Run both binary output files though the flashmap project's own flashmap_decode utility. Observe only the expected differences.
