There are currently two copies of DwarfOp callback tables in
data.rel.ro section, and that is 16KB of dirty memory per process on a
64-bit platform.
To reduce memory usage, we introduce a layer of indirection so that
all instances of DwarfOp can share a single callback table. We also
get rid of the pointers for op names in the callback table so that the
entire table can be placed in rodata section.
Test result shows 1MB saving on cuttlefish, and 750KB saving on a Go
device (32-bit ARM).
Bug: 112073665
Test: Boot on cuttlefish and a Go device.

This commits adds the following two public functions into
class AvbHandle, and verified by 'libfs_avb_test':
static AvbUniquePtr LoadAndVerifyVbmeta(); // loads inline vbmeta.
static AvbUniquePtr LoadAndVerifyVbmeta( // loads offline vbmeta.
const std::string& partition_name, const std::string& ab_suffix,
const std::string& ab_other_suffix, const std::string& expected_public_key,
const HashAlgorithm& hash_algorithm, bool allow_verification_error,
bool load_chained_vbmeta, bool rollback_protection,
std::function<std::string(const std::string&)> custom_device_path = nullptr);
The first function LoadAndVerifyVbmeta() will be used to replace Open(),
in a separate CL in the future. Many libfs_avb internal utils are added
into avb_util.cpp as well, which are verified by
'libfs_avb_internal_test'.

liblp treats the term "block size" ambiguously when it compares the logical
hardware block size with the file system block size (which for all
intents and purposes must be 4K). This warning is thus spurious on
devices with say a 512 logical block size. However, liblp's block size
should at least be a multiple of this, so change the check accordingly.

SetUpDmVerity won't return true twice for the same partition and it will
leads to failure when verify-boot is enabled on multi-fstab-lines.
