To fully and easily implement fallback/recovery in libcbfs with vboot
support the codebase requires access to vboot context. Moving context
management to libpayload allows to avoid unnecessary overhead and code
complication and still allows payloads to access it in a way it was
designed. Access to this codebase will also allow implementation of e.g.
vboot_fail_and_reboot() and other helpful utilities used by coreboot and
depthcharge.

CL:3825558 changes all vb2_digest and vb2_hash functions to take a new
hwcrypto_allowed argument, to potentially let them try to call the
vb2ex_hwcrypto API for hash calculation. This change will open hardware
crypto acceleration up to all hash calculations in coreboot (most
notably CBFS verification). As part of this change, the
vb2_digest_buffer() function has been removed, so replace existing
instances in coreboot with the newer vb2_hash_calculate() API.
Due to the circular dependency of these changes with vboot, this patch
also needs to update the vboot submodule:

Fix the buffer pointer passed to cbfs_file_hash_mismatch().
Add a test case with LZ4 compression, which would catch the bug we are
fixing.

cb_err_t was meant to be used in place of `enum cb_err` in all
situations, but the choice to use a typedef here seems to be
controversial. We should not be arbitrarily using two different
identifiers for the same thing across the codebase, so since there are
no use cases for serializing enum cb_err at the moment (which would be
the primary reason to typedef a fixed-width integer instead), remove
cb_err_t again for now.
