0030953: Data Exchange - implement export of mesh data into glTF 2.0 format

Browse Source 
Added new class RWGltf_CafWriter for exporting XCAF document into glTF file
as well as Draw Harness command WriteGltf.

Added auxiliary method OSD_Path::FileNameAndExtension() splitting file name into Name and Extension.
