soc/intel/meteorlake: Drop FSP CPU feature programming for ChromeOS
The Intel FSP used on ChromeOS platform has dropped the
`CpuFeaturesPei.ffs` module to opt for coreboot running this
additional feature programming on BSP and APs.
TEST=Able to build and boot google/rex without any boot regression.
Please refer to the boot time and SPI flash savings after dropping
the FSP feature programming:
Boot time savings=10ms
SPI Flash size savings=34KB

This is to avoid FSP running basic CPU feature programming on BSP
