[location_rewriter] Handle all AsyncTask execution variants

Since AsyncTask is a base class, the various execute methods are invoked
on the child classes and thus cannot be easily identified by the
location rewriter without re-ordering the build steps. Instead, an
exception is made for executeOnExecutor.

This CL also adds exceptions for executeOnTaskRunner and
executeWithTaskTraits to correctly propagate location when an AsyncTask
is executed using those methods.
