Renderable logic improvements to web viewer (AcademySoftwareFoundatio…

…n#1644) - Adds in proper parsing of renderable elements vs always just picking the first surface shader found. - The test suite files which have (multiple) nodegraph outputs and top level outputs will now load properly. - Adds in UI to mark folders as renderable (using a shaderball icon) - Adds in "soloing" capability to allow picking a renderable and have it show up on all geometry. When nothing is solo'ed the default material assignment is used. - Includes fixes for: - Dag path assignment matching . - Missing exposure of NodeGraph::getDownStreamPorts() in JS. - Addressing the big performance hit when binding materials to geometry in ThreeJS. The code by default is some quite slow code for reflection / debugging purposes which is now turned off. Chess set load is seconds vs minutes. This affects the 'solo'ing workflow significantly as each switch is a geometry re-bind. If the material is not already cached then slow code will be hit which can cause seconds to pass when selecting a new material -- which appears like a "hang" from a user perspective.
