util/cbfstool: Add a new mechanism to provide a memory map

This replaces the mechanism with --ext-win-base --ext-win-size with a
more generic mechanism where cbfstool can be provided with an arbitrary
memory map.

This will be useful for AMD platforms with flash sizes larger than 16M
where only the lower 16M half gets memory mapped below 4G. Also on Intel
system the IFD allows for a memory map where the "top of flash" !=
"below 4G". This is for instance the case by default on Intel APL.

TEST: google/brya build for chromeos which used --ext-win-base remains
the same after this change with BUILD_TIMELESS=1.
