soc/intel/meteorlake: Allow possible options for MP Init

Ported back from commit ceaf9d116949da68aa9c ("soc/intel/alderlake:
Allow possible options for MP Init")

This patch creates choice that lists all possible options to perform
MP Init as below for Intel Meteor Lake platform:
1. MTL_USE_FSP_MP_INIT: Allow coreboot to bring APs from reset and FSP
runs feature programming based and selects MP_SERVICES_PPI_V2 config.
2. MTL_USE_COREBOOT_MP_INIT: Allow coreboot to perform MP Init (both AP
init and feature programming) using native implementation.
Additionally, selects required RELOAD_MICROCODE_PATCH when coreboot
is expected to run MP Init.

Refactor SoC code to allow required FSP UPD override based on
selected MP Init option.

Additionally, added `FIXME` comment to ensure Intel MTL FSP can bring
back SkipMpInit UPD in MTL to let coreboot override this UPD and ensure
independent MP Init flow.
