Update min Vulkan version to 1.0.8.0, and fix various bugs

With updating the SDK, the debug layers also showed multiple bugs.
I have fixed those as well in this CL. These include:

1. Incorrectly tracking the allocated descriptor sets from the descriptor pools

2. Using MemoryBarriers inside render passes.

3. Correctly setting the Stencil Image layout anytime we are using a render pass with a stencil attachment

4. Setting the correct aspect mask for Depth/Stencil in a barrier.
