soc/intel/adl: update libgfx config to a generic eSOL config

This patch updates the early libgfx init config
(MAINBOARD_HAS_EARLY_LIBGFXINIT) used for Alder Lake SoC with a
generic CrOS/ChromeOS early sign of life config (CHROMEOS_ENABLE_ESOL)

This patch does not change the binary or the system behaviour and is
only meant to bind the early GFX initialization with a generic eSOL
config.

BUG=b:352651132
TEST=Able to build google/tivviks and checked the config in output
