drivers/intel/fsp2_0: Add provision to extract FSP Performance Data

This patch enriches coreboot FSP2.0 driver to extract the FSP timestamp
from FPDT (Firmware Performance Data Table) and display right after
FSP-S exits (from `fsp_silicon_init()` function), based on SoC user
selects the required `GET_FSP_TIMESTAMP` config.

The prerequisite to this implementation is to have FSP binary built with
`PcdFspPerformanceEnable` PCD set to `TRUE` to allow FSP to populate
the FPDT HOB.

BUG=b:216635831
TEST=Able to dump FSP performance data with GET_FSP_TIMESTAMP Kconfig
selected and met the FSP prerequisites.
