EmptyConfig objects set JS_STANDALONE=1 by default. However, test tasks that need to run without an objdir
need to be behind an "if not CONFIG['JS_STANDALONE']" condition to avoid causing bustage to sm-pkg task (js
packaging). This patch explicitly deletes that default value, only when generating the TestManifestBackend.
Ideally, the js/src packaging should have their own moz.build instead of re-using the root moz.build. But this
is an easier fix in the short term to get the marionette-harness tests working again.

This replaces the 'run-tests-deps' make target with a python function that will directly
read moz.build files, emit them with TestManifestEmitter, then consume them with
TestManifestBackend. Because the TestResolver is the only place that actually reads the
test metadata files, we can remove this logic from the CommonBackend as well.
