Replace uses of sw::Surface with vk::ImageView in the Renderer

Replace uses of sw::Surface with vk::ImageView in the Renderer

sw::Surface contains a locking mechanism which is no longer required
in Vulkan. The app is now responsible for making sure the lifetime of
the objects is long enough for the driver to be able to use them in
any operation where they are required.

A few shortcuts were taken here:
- ImageView::getSampleCount() currently always returns the largest
  available sample count.
- ImageView::subresourceRange.levelCount is not taken into account
- Context::getMultiSampleCount() still uses attachment 0 to get
  the samples count, which may be incorrect.
