feat(go-feature-flag)!: Introduce in-process evaluation + tracking

[thomaspoignant]

This PR

This is a complete rebuild of the GO Feature Flag provider.
This version is using a webassembly module to do in-process evaluation inside the provider.

You can still use the remote evaluation if you prefer through the OFREP endpoint of GO Feature Flag.

Things to know:

• The wasm module is download during the process-resources of maven using this script.
• The default evaluation method is now the in-process one.
• If you are using the remote evaluation, we are not managing any cache.
• The provider is also now supporting tracking method

@thomaspoignant I'm very interested in this! I don't have time to review today but I will on Friday (not that you have to wait for my approval) since this is all GoFF.

cc @beeme1mr this uses WASM, you might be interested.

This is really cool.

I was worried about making sure all the memory resources were cleaned/closed, but it looks like chicory is doing most of that for you (which is cool). Things make sense to me. Very interested to see how this works at scale.

I left one comment because I think you are possibly missing some Jackson deps.

You might also want to mention tracking in your title.

@thomaspoignant feel free to merge.

I am waiting other major providers to be ready to release them all together.
I am working on .NET and nodeJS.

I forgot that merging does not mean release 🤦
I'll merge it.
