layers: GH690 Save renderPass create info in PSO

The renderPass that a pipeline is created with may be destroyed before
the pipeline is used in a draw. In order to make sure that the renderPass
data will live as long as the pipeline, save the VkRenderPassCreateInfo
using a safe_VkRenderPassCreateInfo in the PIPELINE_NODE struct.
