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

This patch creates choice that lists all possible options to perform
MP Init as below:
1. 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. 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.

BUG=b:233199592
TEST=Build and boot google/taeko to ChromeOS.
