POSIX: gfx::NativeViewId and CrossProcessEvent

Create a couple new typedefs for porting work. Firstly,
gfx::NativeViewId is a handle to a platform specific widget in the
renderer process. For Windows, this is just a HWND as before. However,
in other platforms the ids used in the renderer process will be
something else.

CrossProcessEvent is the type of a HANDLE to a Windows event object
which is used across processes. Since we aren't going to support these
sorts of events on non-Windows platforms, this will have to go away at
some point. For now, however, this lets us build code without too many
ifdefs all over the place.
