Restore applypatch/updater/edify for non-A/B OTA support

Google deleted this source from bootable/recovery outright (commit c7ebad5f, "rm -rf non-AB code", 2024-04-05) — confirmed present at android-14, absent at android-16.0.0_r4. The runtime side (install.cpp's SetUpNonAbUpdateCommands) and build-side packaging (ota_from_target_files.py's GenerateNonAbOtaPackage) both survived; only the source that builds the update-binary executable itself was removed. Sourced from TeamWin's android_bootable_recovery (android-14.1), the only living copy found, with install/ZipUtil.cpp, get_args.cpp, and set_metadata.cpp intentionally left out (only wired into TeamWin's modified install.cpp, which PawletOS isn't adopting — twrpinstall carries its own independent copies). Kept as its own repo, not folded into a recovery fork, so it's buildable independent of whichever recovery UI ends up in use.
