fuzz: Add cifuzz

[manunio]

This PR adds cifuzz action workflow which is a service provided by oss-fuzz where this project already runs, this helps in catching shallow bugs, regression or build breakage by running fuzzers on PR for ~5 minutes (excluding the build time).

Why is it a draft?

Why is it a draft?

I wanted to test something. Will mark it as ready for review.

Am I still going to receive emails if there are issues on the fuzz thingy after this?

Also... I guess the idea is not to run this in every PR? 👀

For oss-fuzz you will still receive emails like earlier, there won't be any changes for that. for cifuzz you will not receive emails, it will report it via github action tab like rest of actions.

Also... I guess the idea is not to run this in every PR? 👀

Idea is to run this on every PR as that helps in catching regression, but this can be restricted to particular branch like release/**.

Do you want to limit the run to releases or a specific branch?

It can be on schedule or on main, but on every PR will be too much for me. Would you mind changing it? 🙏
