Refactors the existing general reflection code to either use Tint or SPIRV-Cross, depending on the backend being used and provided flags. Tint is used when UseTintGenerator is enabled, otherwise SPIRV-Cross is used. For OpenGL, when Tint is used, additional reflection is performed using SPIRV-Cross to support GLSL generation. There still exists backend specific reflection that needs to be implemented in Tint for the complete removal of SPIRV-Cross for non-OpenGL when UseTintGenerator is enabled.
