soc/intel/alderlake: Create eNEM Kconfig for Alder Lake
Alder Lake SoC specific Kconfig that internally selects all eNEM
related Kconfig. CONFIG_ALDERLAKE_CAR_ENHANCED_NEM will get
autoselected if platform doesn't have INTEL_CAR_NEM Kconfig selected
explicitly.
BUG=b:168820083
TEST=Verified CONFIG_INTEL_CAR_NEM is still enable.
