Vulkan: Always reset during createPipelineLayout() We need to always call reset() during createPipelineLayout(), particularly to reset the descriptor pools to handle the new descriptor set layouts that are generated by new immutable samplers. Otherwise, DynamicDescriptorPool::init() will detect that a pool is attempting to be created with a mis-matching descriptor set layout handle.
