marc audy e40e92e484 Shader Compiler: Support for async per-shader DDC queries, and fixes for cancellation of jobs with submit job tasks or async DDC queries in flight. For the latter, a new linked list of pending jobs was added, which jobs are placed in between the time they are created and SubmitJob or DDC queries complete. Cancellation of jobs removes them from the pending list, which the SubmitJob task or DDC completion callback can detect, and skip further processing. It's necessary to ensure cancelled jobs (or in-flight DDC requests stored in those jobs) aren't deleted by going to zero refs when this happens, so the parameter to the SubmitJob task and JobInFlight reference in the job cache data need to be upgraded to reference pointers. ...

Per-shader DDC is now enabled for cooks by default when the preprocessed job cache is enabled, so only that one CVar needs to be toggled to get the full performance benefits.  CVars exist to toggle per-shader DDC during cooks, per-shader DDC for global shaders, and whether per-shader DDC runs async, all set to true.
