CHROMIUM: vendorcode/google: load sar config from CBFS first then VPD

[ Brian: Based on upstream work that may get refactored:
  https://review.coreboot.org/c/coreboot/+/33661/1
  In ToT, we want to drop VPD support. But for old firmware branches, we
  may still need to fix up bad VPD.

Conflicts:
	src/vendorcode/google/chromeos/sar.c
  CONFIG(WIFI_SAR_CBFS) vs. IS_ENABLED(CONFIG_WIFI_SAR_CBFS)
]

SAR config provisioned in RO VPD can be done in the factory only. Once
it is wrong, we can override the SAR config by updating FW RW which can
carry new SAR config in CBFS. As a result, we should check CBFS first
then VPD.
