1.) Move Bindings to own registry 2.) Nuke source files & left over cruft relating to archetypes 3.) Move deprecated interface registration next to respective interfaces for clarity 4.) Rename "FMetasoundFrontendInterfaceBindingConnections" to "FMetasoundFrontendInterfaceVertexBindings" #rb phil.popp #preflight 640f6852d778f889752a5bd1 [CL 24622079 by rob gay in ue5-main branch]
