mb/google/brya/var/ghost: Split ghost4adl into 3 variants

We plan to make 3 firmwares which differ only by Kconfig options and
can share a common variant directory.

ghost4adl: Board with an ADL chip.
ghost4es:  Board near identical but has RPL-ES chip.
ghost:     Will have final RPL silicon.

Since they will only differ by Kconfig options and Intel binary blobs,
let's not duplicate the variant directory but instead share it in
common.

BUG=b:239456576
BRANCH=firmware-brya-14505.B
TEST="make menuconfig", verify layout of board selection
