vo_gpu_next: factor out context-specific code to gpu_next/context.c
This is done to avoid cluttering vo_gpu_next.c with more ifdeffery and context-specific code when additional backends are added in the near future. Eventually gpu_ctx is intended to take the place of ra_ctx to further separate gpu and gpu_next.
