freedreno/ci: enable a630-gles-asan for merge pipeline

The a630-gles-asan job wasn't running in merge pipelines due to a rules conflict in its inherited jobs. But now that it's all fixed up and tests are passing, let's put it back into the pipeline. Also make it more like the other ci jobs and run it with a deqp-runner suite.

@sergi @robclark also thanks @Valentine for pointing this out why a630-gles-asan was not running in merge pipelines !31713 (merged)

Some examples to show that results from running in a merge pipeline is the same as running on a fork

And here is an example of small changes that occur when a630-gles-asan is run using the toml suite
