mb/google/kukui: Introduce a new 'Jacuzzi' family

The 'Jacuzzi' is a different base board that will share most of Kukui
design. For AP firmware, there will be only a few changes expected,
mostly in display (for MIPI bridge) and EC/keyboard so we want to create
it as variants inside Kukui folder, not forking a new directory.

BUG=b:137517228
TEST=make menuconfig; select 'krane' and build; select 'jacuzzi' and build.
