soc/intel/meteorlake: Enable VMX using coreboot CPU feature program

This function calls into `set_feature_ctrl_vmx_arg()`
to enable VMX for virtualization if not done by FSP (based on
DROP_CPU_FEATURE_PROGRAM_IN_FSP config is enabled) in MeteorLake
SoC based platform.

TEST=Able to build and boot google/rex.
