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.
BRANCH=None
