When building with BUILD_FOR_FUZZING=OFF BUILD_FUZZ_BINARY=ON CMAKE_BUILD_TYPE=Debug allow the fuzz binary to execute given test cases (without actual fuzzing) to make it easier to reproduce fuzz test failures in a more normal debug build. In Debug builds, deterministic fuzz behaviour is controlled via a runtime variable, which is normally false, but set to true automatically in the fuzz binary, unless the FUZZ_NONDETERMINISM environment variable is set.
