soc/intel/common: Add fpt_support to override CSME and HECI disables

Intels FPT (Flash Programming Tool) can be used to flash coreboot via
the EFI Shell and various Operating Systems. However, FPT requires
the Intel ME to be enabled, and for the HECI interface to be visible.

Add a runtime option `fpt_support`, which users can use to stop HECI and
the Intel ME from being disabled so this tool will work.

TEST=Boot starbook_rpl with edk2 payload, and flash BIOS region with
FPT.efi.
