Jon Ross-Perkins 60c9b202f6 Relocate fuzzer files and the explorer_fuzzer rule. (#3017)
Putting fuzzer files under //testing to emphasize the testonly aspect
(consolidates bazel and common subdirectories). The attributes on
explorer_fuzzer are also a little skewed from what's desirable; it's
been working okay, but this should still be a refinement.
