bebb637472d0469037a9f438572fc71db4236d97 tests: Add FuzzedDataProvider fuzzing helper from the Chromium project (practicalswift)

Pull request description:

  Add `EvalScript(...)` fuzzing harness.

  To test this PR:

  We can run `contrib/devtools/test_fuzzing_harnesses.sh` (#17000) during five seconds to quickly verify that the newly added  fuzz harness seem to hit relevant code regions, that the fuzzing throughput seems reasonable, etc.

  `test_fuzzing_harnesses.sh eval 5` runs all fuzzers matching the regexp `eval` giving them five seconds of runtime each.

  ```
  $ CC=clang CXX=clang++ ./configure --enable-fuzz --with-sanitizers=address,fuzzer,undefined
  $ make
  $ contrib/devtools/test_fuzzing_harnesses.sh eval 5
  Testing fuzzer eval_script during 5 second(s)
