As discussed in CB:35077, since both measured boot and verified boot
depends on vboot library, it had better to introduce a dedicated flag
CONFIG_VBOOT_LIB to control the building and linking of the vboot
library, and make other flags needing vboot library select it. Only
the actual verification stuff should be conditional on CONFIG_VBOOT.

CB:36845 simplified how coreboot finds the RW CBFS after vboot has and
eliminated a layer of caching. Unfortunately, we missed the fact that
the former cached value didn't exactly match the FMAP section... it was
in fact truncated to the data actually used by vboot. That patch
unintentionally broke this truncation which leads to performance
regressions on certain CBFS accesses.
This patch makes use of a new API function added to vboot (CL:1965920)
which we can use to retrieve the real firmware body length as before.
(Also stop making all the vb2_context pointers const. vboot generally
never marks context pointers as const in its API functions, even when
the function doesn't modify the context. Therefore constifying it inside
coreboot just makes things weird because it prevents you from calling
random API functions for no reason. If we really want const context
pointers, that's a refactoring that would have to start inside vboot
first.)
This patch brings in upstream vboot commit 4b0408d2:

factory_initialize_tpm() calls secdata_xxx_create() (for both firmware

TPM. The create() functions make vboot think it just changed the secdata
(because it reinitialized the byte arrays in the context), so we also
need to clear the VB2_CONTEXT_SECDATA_xxx_CHANGED flags again, otherwise
vboot thinks it still needs to flush the spaces out to the TPM even
though we already did that.
Also clean up some minor related stuff (VB2_CONTEXT_SECDATA_CHANGED
notation is deprecated, and secdata space intialization should use the
same write-and-readback function we use for updates).

The HWID in vboot GBB is an identifier for machine model. On Chrome OS,
that should be provisioned in manufacturing process (by collecting real
hardware information), and will be checked in system startup.
For bring up developers, they usually prefer to generate a test-only
string for HWID. However that format was not well documented and cause
problems. Further more, most Chromebooks are using HWID v3+ today while
the test-only HWID is usually v2. Non-Chrome OS developers may also
prefer their own format.
To simplify development process, the GBB_CONFIG now defaults to empty
string, and will be replaced by a board-specific test-only v2 HWID
automatically. Developers can still override that in mainboard Kconfig
if they prefer v3 or other arbitrary format.
BUG=b:140067412
TEST=Built 'kukui' successfully. Removed kukui GBB config and built
again, still seeing correct test HWID.

With the support of various algorithms and banks in tlcl_extend(),
digest_algo parameter of tpm_extend_pcr() started defining the target
PCR bank in TPM2 case.
The OS expects coreboot to extend the SHA256 bank of BOOT_MODE_PCR.
The value that the OS expects coreboot to extend into BOOT_MODE_PCR
is the SHA1 digest of mode bits extended to the length of SHA256 digest
by appending zero bytes.
Thus the correct value for digest_algo passed into tpm_extend_pcr() for
BOOT_MODE_PCR is TPM_ALG_SHA256.
This didn't matter until adding the support for multiple digest introduced
by patches like https://review.coreboot.org/c/coreboot/+/33252, as
tlcl_extend always used SHA256 bank before.
