drm_hwcomposer: Support multiple AIDL versions

As far as I know, there's no way for Soong to support multiple versions
that will change dependencies based on the Android API version.
However, we can still do that if we build with the aospext project,
making it possible for Android-13 and Android-14 to use the latest
drm_hwcomposer.
