soc/intel/meteorlake: Fill ucode loading UPD if USE_FSP_MP_INIT enable 

This patch calls into a helper function to fill `2nd microcode loading
FSP UPD` if FSP is running CPU feature programming.

This patch is backported from
commit fad1cb062e (soc/intel/alderlake:
Fill ucode loading UPD if USE_FSP_MP_INIT enable).
