mesa: add ARB_framebuffer_no_attachments named functions
The wording in ARB_framebuffer_no_attachments and EXT_direct_state_access is different. In the former framebuffer names must have been generated using glGenFramebuffers before using the named functions. In the latter framebuffer names have no such constraints, so we can't use the _mesa_lookup_framebuffer_dsa function. Reviewed-by: Marek Olšák <marek.olsak@amd.com>
