[Feat] (MG_Impl, MG_Util): STENCIL_INDEX8 renderbuffers; report distinct D/S renderbuffers unsupported

Browse Source 
GL_STENCIL_INDEX8 becomes a first-class internal format (VK_FORMAT_S8_UINT
backing, metrics, classifiers, converters), so glRenderbufferStorage
accepts it instead of leaving GL_INVALID_ENUM behind. Framebuffer
completeness now also mirrors the renderer's gate for renderbuffers:
distinct depth/stencil renderbuffer attachments (or a renderbuffer
paired with a texture) report GL_FRAMEBUFFER_UNSUPPORTED - the spec only
requires the same-image case - instead of passing completeness and then
failing at draw/clear (verify_mixed_attachments.* now passes).
