vboot2: add verstage
This reverts the revert commit 5780d6f3876723b94fbe3653c9d87dad6330862e
and fixes the build issue that cuased it to be reverted.
Verstage will host vboot2 for firmware verification.
It's a stage in the sense that it has its own set of toolchains,
compiler flags,
and includes. This allows us to easily add object files as needed. But
it's directly linked to bootblock. This allows us to avoid code
duplication for stage loading and jumping (e.g. cbfs driver) for the
boards
where bootblock has to run in a different architecture (e.g. Tegra124).
To avoid name space conflict, verstage symbols are prefixed with
verstage_.
TEST=Built with VBOOT2_VERIFY_FIRMWARE on/off. Booted Nyan Blaze.
BUG=None
