[fuzztest] Enable sharing fuzztest outside of Chromium
For using the fuzztest dependency in V8, we also need its BUILD.gn
file.
To avoid forking the file, we plan to include it as separate
copybara repo. This, however, depends on boringssl and
libFuzzer which both are further intertwined with Chromium
sources, not available in V8. Since they aren't required to build
fuzztest with centipede, this puts them behind the
build_with_chromium flag, as done in several other dependencies.
Within Chromium, this change should be a no-op.
