window: move buffer type and transform into struct surface
These are surface specifics, since buffers are surface specific.
SURFACE_HINT_RESIZE is moved together to the other SURFACE_* flags, so
that surface_create_surface() would not need two flags arguments.
struct toysurface::prepare vfunc checks for SURFACE_HINT_RESIZE, and
egl_window_surface_create() and shm_surface_create() check for the
non-HINT flags.
