Generate Android.bp and dependencies with LineageOS's GenerateBp plugin

...extract all common dependencies to a new module, app-deps, and then
run LineageOS's GenerateBp plugin based on that. The resulting
Android.bp file is a java_defaults that can be used from the main
Android.bp.

Note that the prebuilt binaries are placed in app-deps/libs by
GenerateBp. This directory is explicitly excluded by .gitignore. These
binaries should be copied to another repository
(android_prebuilts_openeuicc-deps) manually.
