Add support for edit commands in OOPIFs.

Add support for edit commands in OOPIFs.

Previously, edit commands from the browser were sent via
InputMsg_SetEditCommandsForNextKeyEvent to focused RenderWidgets, but
for OOPIFs the IPC was dropped since it was only handled in
RenderViews.  To fix this, this CL moves the IPC handling and
associated edit command bookkeeping to RenderWidget.
