feat(build): use mise to manage third party tools

[pmalek]

What this PR does / why we need it:

This PR adapts Kong/gateway-operator#17 to KIC's repo to manage dependencies using mise.

This leaves out several tools that still require the third_party's go.mod because there are no plugins for mise in https://github.com/mise-plugins/registry for those tools and I didn't want to wait too long with this change.

If anyone would like to create a plugin for any of those:

• looppointer
• staticcheck
• or dlv

I'm happy to help. Here's an example what that looks like: https://github.com/pmalek/mise-setup-envtest/.

---

Also adds renovate annotations to .tools_version.yaml and a corresponding config section.

Tested on fork: pmalek#22.

I think that Go 1.22 will enable by default remediation, so it will make looppointer obsolete. So it's not a big deal, we can even enable this with env var now
