This PR moves all the OSS-Fuzz fuzzers to the upstream storage for easier management. This PR works together with OSS-Fuzz (google/oss-fuzz#16308) to accommodate the moving of fuzzers upstream.

Of course, this is only a suggestion. If the maintainers would prefer the fuzzers to remain in OSS-Fuzz, I am happy to keep the current setup and to ping the relevant maintainers for review whenever I add new fuzzers later in the process.

Thank you for considering this, and I would welcome any feedback on the preferred approach.

Remark: After this PR is accepted and merged, there will be additional PRs for adding new fuzzers for this project later.

Summary

Moves the protobuf-based fuzzer sources upstream and adds an optional standalone fuzz target.

• Developers can build the raw-byte fuzzer without the regular tests.
• Structured inputs now let OSS-Fuzz exercise JsonCpp’s parser.
