add target_compatible_with stanza for host targets

Soong modules that are specific for the host platform (e.g.
java_library_host, cc_binary_host, java_genrule_host, etc.) should
not be built on the target platform (Android), so we add a
target_compatible_with attribute to skip this type of module on an
Android target build.
