Improve generate_build_files.py gn support.
Split gn and gyp generators apart. Since we're pre-generating files, there's no need to make BoringSSL's build depend on the gypi_to_gn.py script. Also emit the tests and a list of fuzzers so we don't need to manually update BUILD.gn each time. The new gn generator is based on the bazel one since they're fairly similar.
