Bazel: Remove redundant plugin build boilerplate

Recent bazlets changes let gerrit_plugin() resolve Maven coordinates
passed through ext_deps against the default <plugin>_plugin_deps
repository.

They also let gerrit_plugin_tests() derive the default test target name,
wire the plugin under test, resolve external test dependencies from
ext_deps, and generate the runtime dependency checks when plugin is set.

Use those macro defaults in owners-common-api instead of spelling out
artifact() conversions and dependency test rules locally.
