Atom Tools: Changed ME preset browser dialog into generic asset grid dialog in ATF
Moving more potentially shared code out of the material editor into atom tools framework. This change consolidates the lighting preset browser, model preset browser, and the base dialogue that they shared into a single, grid based, asset selection dialog. AssetGridDialog should appear as a move and rename of PresetBrowserDialog but there are probably too many differences with new variable renames and SelectableAsset struct. Along the way I found examples showing that event bus broadcast accepted generic functions and lambdas. Used this to do a minor cleanup of the viewport settings inspector where the preset dialogs were initialized and other places that did several back to back bus calls.
