Completes the GetWindowRect/GetRootWindowRect/GetScreenInfo changes I thought I had finished with my last CL.

. Disable a check in BrowserMessageFilter that these messages are not handled on the UI thread, for Aura. In Aura, these messages need to be handled on the UI thread (since aura::Windows are not threadsafe). We do not have the NPAPI plugin constraints regular windows has, so this check is not important.
. Properly handle these messages in RWH, by sprinkling in some more defined(USE_AURA) to go with the defined(OS_POSIX).
. Properly define RenderWidgetHostView::GetDefaultScreenInfo() (it was being done as an override to a static?.. oops).
. Get rid of the USE_AURA NOTIMPLEMENTED() definition of the above in render_widget_host_view.cc, replacing with an impl in rwhva.cc. Also moves the _mac and _touch variants to their own .mm/.cc files.
. Gets rid of WillWmDestroy for Aura. It's normal-windows-only.

As it happens, it's not possible to move the touch definition to RWHVV_touch,
duh, it's not in content. We can remove this once RWHVV is dead.
