[Gpu] Collect an image only once it is old enough in frames 

Since images age by frame, clamping the age to the current frame made every
image of the first frame collectable during the first 16 frames, and a
submission that ended no frame could delete a texture the frame still used.
Without memory pressure nothing is collected until the full age has passed;
under pressure the clamp still lets collection relieve memory early.
