Some apex payload images contain apk files. And these apks need to be
signed during the signing processed when sign_target_files_apks is
called. To support the signing, we can extract the payload and repack
the apex file with the (de)apexer tool. Add the signing support in the
apex_util.

The commit in d14b895665
(https://android-review.googlesource.com/c/platform/build/+/728287)
changed partition layout, to always build the root dir into system.img,
even for devices not using system-as-root (i.e. the ones with separate
boot ramdisk).
With the new layout, there will be two root dirs for non-system-as-root
targets during the boot. If such a device uses Verified Boot 1.0,
/verity_key needs to be available in both roots, to establish the chain
of trust.
- bootloader uses the baked-in key to verify boot.img; it then loads
the ramdisk from the verified boot.img
- First stage init uses /verity_key (in ramdisk) to verify and mount
system.img at /system, then chroot's to it
- Second stage init uses /verity_key (in system.img) to verify and
mount other partitions
This CL adds rules to additionally install verity_key into ramdisk for
such targets.

sign_target_files_apks.py only needs to take care of the current
release. The legacy paths of ODM/build.prop, VENDOR/odm/build.prop, and
BOOT/RAMDISK/default.prop no longer exist in the target_files.zip from
master.
The other two cases of ROOT/default.prop and
RECOVERY/RAMDISK/default.prop are still kept in the code, as they will
still exist (as symlink or conditionally).

In device root directory, we have the following symlinks:
- /odm/app -> /vendor/odm/app
- /odm/bin -> /vendor/odm/bin
- /odm/etc -> /vendor/odm/etc
...
This allows the Generic System Image (GSI) to be used on both devices:
1) Has a physical odm partition, where those symlink will be hidden
when /odm is used as the mount point
2) Has no physical odm partition and fallback to /vendor/odm/.
We can't just have the symlink /odm -> /vendor/odm, because the former
devices won't have /vendor/odm directory, which leads to mount failure
when the mount point /odm is resolved to /vendor/odm.
The existing /vendor/odm/build.prop won't be loaded in the latter
devices, because there is no symlink:
- /odm/build.prop -> /vendor/odm/build.prop.
Note that init blocks reading through direct symlinks (O_NOFOLLOW) so
the above symlink won't work either. This CL moves the odm build.prop
to /odm/etc/build.prop for init to load it (symlinks in earlier
components of the path will still be followed by O_NOFOLLOW).

Previously it was following a wrong order by doing `zipalign` after

- Call SignApk to sign the container with `-a 4096` flag.

Currently system_other AVB public key is placed in system.img.
However, this makes it's harder to have a *generic* system.img
across different product configs. Moving the key to /product
partition to allow more product-specific AVB keys.
Device board config can add /product/etc/fstab.postinstall,
to mount system_other with this key in /product. It can specify
different mount options, file systems, verity settings, etc., in
this product-specific fstab as well.

We may pack prebuilts that end with ".apk" into target_files zip, via
PRODUCT_COPY_FILES. META/apkcerts.txt won't contain the cert info for
such files, and we want to keep them as is while signing, despite of the
".apk" extension.
This CL adds "--skip_apks_with_path_prefix" option to
sign_target_files_apks.py. APKs with matching prefixes will be copied
verbatim into the signed images. The prefix should match the entry names
in the target_files (e.g. "SYSTEM_OTHER/preloads/"). The option may be
repeated to specify multiple prefixes.
Note that although we may skip signing an APK file with "-e ApkName=".
This would skip *all* the APK files with the matching basename.
"--skip_apks_with_path_prefix" allows matching the exact prefix.
For example:
$ ./build/make/tools/releasetools/sign_target_files_apks.py \
--skip_apks_with_path_prefix SYSTEM_OTHER/preloads/ \

When calling 'openssl x509 -pubkey' to extract the public key from a

check_ota_package_signature.VerifyAbOtaPayload(). This CL addresses
the issue by always collecting the output from stdout instead.

For devices using derived fingerprint (i.e. /system/build.prop doesn't
contain ro.build.fingerprint, but has ro.build.thumbprint instead), the
current code (in android.os.Build) doesn't have a matching logic to do
the same for ro.vendor.build.fingerprint. This means we will see
ro.build.thumbprint in /system/build.prop, while there's no matching
ro.vendor.build.thumbprint in /vendor/build.prop.
From signing script point of view, it should just apply the tag
