This change is part of a topic that moves the recovery resources from the
system partition to the vendor partition, if it exists, or the vendor directory
on the system partition otherwise. The recovery resources are moving from the
system image to the vendor partition so that a single system image may be used
with either an A/B or a non-A/B vendor image. The topic removes a delta in the
system image that prevented such reuse in the past.
The recovery resources that are moving are involved with updating the recovery
partition after an update. In a non-A/B configuration, the system boots from
the recovery partition, updates the other partitions (system, vendor, etc.)
Then, the next time the system boots normally, a script updates the recovery
partition (if necessary). This script, the executables it invokes, and the data
files that it uses were previously on the system partition. The resources that
are moving include the following.
* install-recovery.sh
* applypatch
* recovery-resource.dat (if present)
* recovery-from-boot.p (if present)
This makes the applypatch executable a vendor module.
This change supports making dependencies of the applypatch executable available
to applypatch, which is now on vendor.
Since install-recovery.sh is now a vendor service, we add the
applypatch/vendor_flash_recovery.rc file to /vendor/etc/init to start the
service.

Test: Ensure that recovery partition is updated correctly.

Prior to this CL, applypatch was the only user of libbrotli.so and
libbz.so (update_engine and puffin have been using the static versions).
This CL switches applypatch to their static versions to save space in
/system.
Sizes prior to the change (aosp_taimen-userdebug):
/system/bin/applypatch 91296
/system/lib64/libbrotli.so 688536
/system/lib64/libbz.so 79560
After:
/system/bin/applypatch 272368
Test: `m dist`
Test: Check the built blueline-userdebug target. libbrotli.so and
libbz.so are not installed.

Prior to the change, SystemUpdaterSample was built as privileged app.
It must be installed along with the matching privapp-permissions
whitelist change (as noted in updater_sample/README.md), otherwise would
block device booting if installed unintentionally (e.g. with `mm` or
`mmma`).
This CL avoids putting the device in a bad state due to a sample app.
Fixes: 135703777
Test: `lunch aosp_taimen-userdebug && m -j installclean &&
mmma -j bootable/recovery && m -j`
Flash on device and boot successfully.
Test: Run the tests per instructions in updater_sample/README.md.

Most of the tests in component/ are in fact unit tests. And it doesn't
look practically beneficial to distinguish between the two:
- They have the same test setup;
- We always run both (recovery_unit_test and recovery_component_test)
at the same time;
- Breaking any of them would be equally bad.
This CL merges the tests in recovery_component_test into
recovery_unit_test to save the effort to maintain both.
Test: Run recovery_unit_test on marlin (via `adb sync data`).
Test: `atest recovery_unit_test`

It was once considered to be shared between recovery and minadbd, so
that the latter can start an install on its own. The plan has been
changed, since package install -- including device wipe operations --
could be device-specific, which should be done by recovery only.
This CL moves libinstall back to a static library, which also saves the
overall size (reducing from 140256 + 660576 to 555880 bytes on
aosp_taimen-userdebug).
Bug: 130166585
Test: Run recovery_component_test.
Test: `adb sideload` on taimen.

It also reduces the space cost for devices using f2fs (e.g. crosshatch).
/sbin/mkfs.f2fs 722560 => /system/bin/make_f2fs 49568
/sbin/sload.f2fs 1182456 => /system/bin/sload_f2fs 150032
Test: Build and boot recovery on crosshatch. Factory reset.
Test: Install a non-A/B OTA package that formats a f2fs partition.
