ANDROID: Unroll define_common_kernels().
We prefer DAMP over DRY build files. Unrolling the macro allows us to provide more flexibility towards multi-KMI, e.g. when we need to enable ABI monitoring on additional targets. It also makes auto-completion in terminals work better. Bug: 256196254 Change-Id: I1a809f80e4b1dbffc88a933144bde788cec67683 Signed-off-by: HONG Yifan <elsk@google.com>
