Add missing mojo dependencies that were causing mojo_apptest hangs.

I logged into one failing machine and ran "mojo_runner --use-headless-config --gtest_filter=ViewManagerTest.RootView mojo:view_manager_apptests". The test printed that it passed but then hung. The output had "[0525/201523:ERROR:default_logger_impl.cc(46)] validation_errors.cc(61): Invalid message: VALIDATION_ERROR_UNEXPECTED_STRUCT_HEADER". This is because a component had a different version of the mojom serialization. Tracking down the build dependencies, it was because view_manager didn't depend on surfaces, and also mandoline:tests needed to depend on view_manager:apptests. I verified that building mandoline:tests on a broken bot fixed this.

I looked through all the apptests to make sure there were no other missing dependencies. I also removed an unnecessary "$default_toolchain)" in clipboard's build file.
