524fe03bfb backuptool: introduce addon.d script versioning
* Since A/B addon.d scripts are going to need to do things in a
  specific way or things could go horribly wrong for a user, let's
  introduce versioning so that scripts can claim to be compatible.

* A script can denote it is compatible with addon.d version 2 by
  adding: "# ADDOND_VERSION=2" somewhere in its script.

* Only A/B will require version 2 scripts for now, and version 2
  scripts will still run on non-A/B. Additionally if a script does
  not explicitly denote its version, assume its version 1.

* Version 1: The same old scripts we've always used. We cannot assume
             these will all work with A/B backuptools.

* Version 2: Scripts that denote they are compatible with version 2
             must be aware of the fact that A/B devices will run this
             script for a rom, during a seamless update, mounted at
             /postinstall. The best way to ensure compatibility would
             be to use the pre-designated functions found in the
             backuptool[,_ab].functions scripts.

4a049b563c vendor: add custom backuptools and postinstall script for A/B OTAs
* A/B OTA devices wont run backuptools in recovery (because they don't
  go in to recovery to do an OTA). In these cases let's use a modified
  version to backup/restore from within android upon postinstall.

* Add backuptool_postinstall.sh which will be run prior to the normal
  postinstall script in order to backup/restore via addon.d scripts.

* This needs to be done in such a manner because we need /postinstall
  mounted rw instead of the ro with context= options which are used for
  the normal postinstall (dexopt) script.
