libavb: update to AOSP 1.3.0

Re-sync the vendored libavb from AOSP external/avb, moving from the ~2019
snapshot (v1.1.0) to v1.3.0. v1.1.0 rejected any vbmeta whose required
libavb minor version was greater than 1 with UNSUPPORTED_VERSION; this
lifts that ceiling and picks up the accumulated upstream fixes.

Synced from commit a1fe228b8654 ("libavb: support chain partition no ab"),
which is where AVB version 1.3.0 was introduced; the vendored files match
this commit verbatim except for the -Wstrict-prototypes fixup noted below.
For more details check [1].

Functionality now parsed by the library:
  - AvbVBMetaImageHeader.rollback_index_location (v1.2)
  - AvbChainPartitionDescriptor flags / DO_NOT_USE_AB (v1.3)
  - AvbHashtreeDescriptor FLAGS_CHECK_AT_MOST_ONCE
  - AVB_HASHTREE_ERROR_MODE_PANIC

The AvbOps callback set is unchanged, so the integration layer in
common/avb_verify.c needs no changes.

U-Boot-specific adaptations are preserved rather than pulling upstream's
BoringSSL-oriented crypto restructure (sha/, boringssl/): the U-Boot port
in avb_sysdeps.h / avb_sysdeps_posix.c and the flat avb_sha.h /
avb_sha256.c / avb_sha512.c are kept as-is. The SHA API signatures are
unchanged, so the retained implementation is compatible with the updated
code.

Imported files keep U-Boot's SPDX-License-Identifier header style
and their upstream per-file licenses (avb_rsa.c stays MIT OR
BSD-3-Clause). The unused, Apache-2.0-licensed avb_crc32.c is not
imported.

The import keeps U-Boot's existing local fix from commit fbfcb614e05
("libavb: Fix a warning with clang-15"): avb_new_cmdline_subst_list() is
kept with a (void) parameter list instead of reverting to upstream's
empty () form, which clang rejects under -Werror,-Wstrict-prototypes.
