Detailed Description

Defines an operations and memory access barrier on a resource.

        For further reading, see
        https://www.khronos.org/events/vulkan-how-to-use-synchronisation-validation-across-multiple-queues-and-command-buffers
        and the Vulkan spec. The docs for the various member of this
        class are based on verbiage in the spec.

        A useful mnemonic for building a mental model of how to add
        these barriers is to build a sentence like so; "All commands
        before this barrier may continue till they encounter a <src
        access> in the <src pipeline stage>. And, all commands after
        this barrier may proceed till <dst access> in the <dst pipeline
        stage>."
