drm_fb: use shadow buffers when device prefers it
I noticed the sdl_fb backend seemed to often have significantly better FPS in fullscreen use vs. drm_fb fullscreen. Looking at the libdrm api I saw this PREFER_SHADOW capability and noticed my laptop's gpu driver sets it... With this change, despite the additional memcpy(), the drm fullscreen FPS seems significantly better. A subsequent commit will make this an overridable runtime setting
