vboot: changes to allow RW_LEGACY hash verification
This is largely a cherry-pick of CL:1133598
- Externalize vb2_digest_buffer function to vb2api_digest_buffer.
- Change VbExLegacy()'s altfw_num parameter from int to enum so
caller can specify which specific payload to run.
BUG=b:124358784
BRANCH=None
TEST=Local compile. Verified with subsequent change that legacy boot
still works and new functionality can opt-in to and utilize payload
verification.
