Create new android_host_service_fixture rule.

This rule specifies a host binary that is run as part of an android_instrumentation_test. It merely collects options, support APKs and the runfiles for the host binary and passes them along to the upcoming android_instrumentation_test rule.

Note that this CL does _not_ install the rule, so this CL does not make it usable by anyone. Once the other android testing rules are ready, we will install them all.

One small step towards https://github.com/bazelbuild/bazel/issues/903.
