Which issue does this PR close?

Closes #3350

Rationale for this change

The fuzz-testing Maven module is a standalone tool that has fallen out of regular use. Its functionality overlaps with the in-process CometFuzz*Suite tests under spark/src/test, which provide ongoing fuzz coverage as part of CI.

Also, we have found that using LLMs to perform audits of Spark vs Comet code and generate tests for edge cases has been far more effective than this fuzz testing module.

What changes are included in this PR?

Remove the abandoned fuzz testing module.

How are these changes tested?

N/A

Remove the standalone fuzz-testing module along with its references in
pom.xml, .dockerignore, kube/Dockerfile, and the spark_sql_test and
iceberg_spark_test workflow paths-ignore lists.
