Elias Naur b942e4035b piet-gpu/shader: ensure forward progress in decoupled lookback 
The Vulkan and OpenGL specifications offer only weak forward progress guarantees, and
in practice several mobile devices fail to complete the decoupled lookback
spinloop without mitigation.

This patch implements Raph's suggestion from the "Forward Progress"
section from
