faa4ab113cc9e300b3b8dce0c774d0a33a555883 ci: Drop valgrind fuzz from GHA matrix (MarcoFalke)
Pull request description:
The valgrind fuzz task is problematic, because:
* It is redundant with the msan fuzz task, which has std lib hardening enabled, so often UB is diagnosed before it even happens in the valgrind task.
* All issues so far found by the valgrind fuzz task were also found by the hardened msan fuzz task.
* All other issues were false-positives, which are hard to debug, and confusing and tedious to work around.
I don't think there is any value in asking pull request authors to debug valgrind false-positives that they triggered by accident. So remove the task for now.
I know that there are some devs, who like to keep the task, but if the task is kept, it should come with clear instructions on how to deal with false-postives in pull requests.
I am not proposing to remove the config itself, and I am happy to continue maintaining it, like it was done before. However, as of now, running it in the GHA matrix is of negative or questionable benefit.

ACK faa4ab113cc9e300b3b8dce0c774d0a33a555883 - hopefully we can revisit re-adding soon. To be clear, I don't agree with the rationale from #34304, or the initial changes there. The case here, and the fact that it is causing disruption in this repo, is more pressing.
