Reviewed by Ryosuke Niwa.

Our DumpRenderTree should support --no-timeout and --timeout options in order
to be able to use run-perf-tests and have a Performance Bot.
This patch adds setTimeout and setShouldTimeout functions to our LayoutTestController
and the necessary code to handle such command line arguments to our DumpRenderTree.
