Step 2 of #2519, modelled on diesel-rs/diesel#5212.

Adds the ClusterFuzzLite configuration and four workflows for the existing fuzz_parse_sql target.

Every pull request fuzzes for 10 minutes in code-change mode, pushes to main refresh a runner-cached build, and a daily batch at 06:00 UTC plus a corpus prune at 05:00 keep the shared corpus on the clusterfuzzlite branch of this repository using the default GITHUB_TOKEN.

Given this is the first time we actually start to fuzz the code automatically and the various PRs, I expect some blood bath of bugs will ensue, but that is sort of the point. We will add more fuzz harnesses over time.

A bit unexpected, but no crash on the first fuzz makes sense given how weak is the current harness. The next PRs will bring better harnesses and a decent seed body.
