mb/google/rex: Update FMD to incorporate ISH firmware

This patch adds two new chromeos_*.fmd files for release and debug FSP
builds targeting rex_ec_ish.

`rex_ec_ish` variant would pack ISH firmware into the CSE boot partition
hence, the blob size is expected to increase. Creates separate flash map
layout to ensure ISH work is not impacting on the regular `rex0` project
SPI flash usage.

BUG=b:284254353
TEST=Able to build google/rex_ish_ec board and boot on target hardware.
