Update from 7.55.1 to 7.57.0

Update the local patch to match the new config. Removed the
packages/Android/Android.mk file added by upstream (outdated Android.mk
version which will confuse people). Updated Android.bp with the new files.

Bug: http://b/70741465
Test: builds, boots, `vendor/google/tools/fake-ota on streaming` works
