Vulkan: Remove support for render passes

Browse Source 
Vulkan 1.0 render passes have been replaced by dynamic rendering in 1.2.
Blender Vulkan backend was implemented with dynamic rendering in mind.
All our supported platforms support dynamic rendering. Render pass support
was added to try to work around an issue with legacy drivers. However these
drivers also fail with render passes.

Using render passes had several limitations (blending and some workbench
features were not supported).  As no GPU uses it and it is quite some code
to support it is better to remove it.
