The idea is that we'd move the installation and packaging tasks over to it, using data from Soong & the Kati reading Android.mk files. This would allow us to make more fundamental changes about how we package things without having to adjust makefiles throughout the tree. Possible use cases: * Moving some information from Soong's Android.mk output to a file read by the packaging step may allow us to read the Android.mk files less often, speeding up builds. * Refactoring our current two-stage ASAN builds to run the Kati build step twice, writing into different object directories, then have a single packaging step that reads both outputs. Soong already has the capability of writing out a single ninja file with all the asan combinations. * Running two build steps, one building the system-related modules using a "generic" device configuration, and one building the vendor modules using a specific device configuration. This could enforce a GSI/mainline system vs vendor split in a single build invocation. * If all installation is through this tool, it will be much easier to track what should no longer be installed on an incremental build, reducing the need for installclean. * Changing PRODUCT_PACKAGES should be a much faster operation, which means we could keep track of local additions to the images. Then `mma` would be more persistent, instead of installing something once, then never updating it again. Eventually we plan on switching from Kati to something Go-based, but this is a more incremental approach while we clean up everything else. Currently, this just moves the dist-for-goal handling over to the packaging step, so that we don't need to read Android.mk files when DIST_DIR changes, or we switch between dist vs not.
