Test for Pepper IME events.

This patch adds a way to simulate IME composition events
inside the renderer process, and tests that IME events are
properly passed between the renderer and plugins.

ppapi/tests/test_ime_input_event.cc:
is the actual test case

ppapi/{api,c,cpp}/dev/*ime_input_event_dev*:
implements an API to create IME events from plugins for testing.

other files:
wire necessary stuff for simulating IME events.
Since Pepper IME events are not delivered through WebKit/DOM layer
but rather directly sent from renderer to plugins,
the simulation part also follows the similar code path.
