commit dbfda411da390ce3923a6ea935c3fa056143d3c9

[fuchsia] Add support for on-screen keyboard input.

This patch allows the user to input text in Frames using Fuchsia
IME's on-screen keyboard.

All input event conversion logic is moved to a helper library
"InputEventDispatcher", which takes events from the hardware keyboard
and on-screen keyboard event handlers.

Add platform-specific IME hide/show hooks to RenderWidgetHostViewAura.
