soc/intel/common: Refactor FSP-M early Sign-of-Life (SoL) settings

This commit centralizes the configuration of the Firmware Support
Package for Memory (FSP-M) early Sign-of-Life (SoL) into a common
function to reduce code duplication and enhance maintainability.

This refactoring aims to improve code readability and reduce potential
bugs by having a single source of truth for SoL configuration across
different platforms.

Since the Updateable Product Data (UPD) definitions for VGAInitControl
differ between Meteor Lake and Panther Lake, and because the list of
currently supported uses also varies between the two, the
decision-making process is still being conducted within the SoC (System
on Chip)-specific codebase.

TEST=FSP-M early SoL functionality was verified on Panther Lake
     platform.
