CMake: Handle building fuzzer with sanitizers

If any of the `CPPDAP_?SAN` sanitizers are enabled, then the build would fail as the compile flags would collide with hard-coded use of address sanitizer for the fuzzer.

Don't hard code address sanitizer for the fuzzer - just use the CMake flag options.
