releasetools: Add AbOtaPropertyFiles.
AbOtaPropertyFiles writes 'ota-property-files' into package metadata.
Comparing to StreamingPropertyFiles, AbOtaPropertyFiles additionally
writes a token of 'payload-metadata.bin' for a virtual entry that's head
of the 'payload.bin'. This entry can be used by the system updater to
verify if a payload is applicable to the underlying device.
AbOtaPropertyFiles intends to replace StreamingPropertyFiles, as it
covers all the info of the latter. We keep them both in P, and will
remove the latter in later release.
Bug: 74210298
Test: python -m unittest test_ota_from_target_files
Test: Generate full and incremental A/B OTAs. Check the property-files
in the METADATA entry.

This is the Makefile-based portion of the Android Build System.
For documentation on how to run a build, see Usage.txt
For a list of behavioral changes useful for Android.mk writers see Changes.md
For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.
This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
