v4l2_codec2: Convert Android.mk for libv4l2_codec2_vda and libv4l2_code2_arcva_factory to Android.bp

libv4l2_codec2_vda and libv4l2_code2_arcva_factory are required to be imported by
device/google/cheets/codec2/allocators/Android.bp. The allocators is also required to be imported by
device/google/cheets/codec2/vdastore/Android.bp.
Because shared library built by Android.mk is not visible by Android.bp. There is a need to convert
Android.mk buidling libv4l2_codec2_vda and libv4l2_codec2_arcva_factory to Android.bp.
