cbfs/vboot: remove firmware component support
The Chrome OS verified boot path supported multiple CBFS instances in the boot media as well as stand-alone assets sitting in each vboot RW slot. Remove the support for the stand-alone assets and always use CBFS accesses as the way to retrieve data. This is implemented by adding a cbfs_locator object which is queried for locating the current CBFS. Additionally, it is also signalled prior to when a program is about to be loaded by coreboot for the subsequent stage/payload. This provides the same opportunity as previous for vboot to hook in and perform its logic. BUG=chromium:445938 BRANCH=None TEST=Built and ran on glados.
