Make the `ContentPresenter.Content` property depend on `ContentPresenter.ContentTemplate` because otherwise a temporary control will be created by the presenter using the default template between the time `Content` and `ContentTemplate` is bound.
However, because Portable.Xaml doesn't actually _support_ `DependsOnAttribute` yet, also move the bindings for `ContentTemplate` above `Content` in the default themes.
This works around #1271 although #1284 fixes the underlying cause of the leak - this is more to prevent unnecessary controls being created.
To the owner control's Content property. In WPF this is done
automatically, but from looking on the internet it seems that causes
some confusion so do it explicitly.
Fixes#499 .
