Move fuzzers to testing/fuzzers.
Move them out of testing/libfuzzer, to make it possible to pull libfuzzer into that directory. Leave testing/libfuzzer/BUILD.gn there for now as a transitional build file. BUG=pdfium:1088 Change-Id: I4126d89dd3e075ac63477a4860e029c135866dbe Reviewed-on: https://pdfium-review.googlesource.com/32896 Commit-Queue: Lei Zhang <thestig@chromium.org> Reviewed-by: dsinclair <dsinclair@chromium.org>
