freedreno/ci: convert a630-gles-asan to toml suite
Currently a630-gles-asan is running deqp-runner directly rather than
through a toml suite configuration
Convert a630-gles-asan to use a toml suite. This makes it similar to other
freedreno jobs. The two substantive consequences are:
* it runs tests in default groups of 500 instead of 5000
* it skips tests listed in `freedreno-a6xx-skips.txt`
