mb/google/rex: Create variant to support ISH enablement 

This patch creates a new variant to support the ISH enablement using
Rex platform.The idea here is to leverage the `rex0` code as much as
possible and add specific support for ISH enablement as per the hardware
schematic differences.

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