content: Move render_widget_host_view_gtk to content/

This also moves some other files:
- OwnedWidgetGtk now goes in ui/base/gtk/
- TruncateString moved from l10n_util:: to ui::
- GtkIMContextWrapper has part of its code split into chrome/ (IDC using code goes in RenderViewContextMenu) and the rest go in content/ (gtk using code goes with GtkIMContextWrapper).
- gtk_key_bindings_handler[_unittest] now goes in content, as it's a utility class to RenderWidgetHostGtk.

This patch has already gotten too big. I should have tried moving some of the
dependencies first, but didn't know about them. This patch would have been much
smaller if I could have committed w/ "chrome/" includes in content/.

BUG= ?

would it be possible to split this up for review? it's a bit daunting

gyp changes look fine to me, at least.
