Client API: use only system backend in the android tree
This change makes the client library backends selectable with GN.
This is achieved by splitting out the client_api_base target and
pairing it with either the real backends or with fallback versions
that return nullptr nad print an error.
This is to avoid linking the in-process backend (which in turn pulls
all the consumer and service code) on Android.
Saves 214KB of binary size in Android.
