cpu/intel/microcode: Have API to re-load microcode patch
This patch introduces a newer API to reload the microcode patch when
SoC selects RELOAD_MICROCODE_PATCH config.
Expected to call this API being independent of CPU MP Init regular
flow hence, doesn't regress the boot time.
BUG=b:233199592
TEST=Build and boot google/kano to ChromeOS.
