Generalize OutputPresenterFuchsia

The current OutputPresenterFuchsia is tightly coupled with using the
Ozone scenic backend. Change OutputPresenterFuchsia to use existing and
new Ozone APIs to be serve as a base for general Ozone+Vulkan
presentation. The immediate goal is support both Ozone+Fuchsia scenic
and flatland backends.

The buffer allocation is switched to use the existing
SurfaceFactoryOzone::CreateNativePixmap() method. The presentation of
primary+overlay planes is moved to a new
PlatformWindowSurface::Present() method.

OutputPresenterFuchsia could become something like
OutputPresenterVulkanOzone in the future, since there is almost nothing
specific to Fuchsia left in it.
