feat(ecs): add negative tags

[RiscadoA]

Description

Adds the .noTag and .noStartupTag methods to Cubos, analogs to .tag and .startupTag but which can be used to apply configuration to all systems except the ones with the given tag. This was implemented by simply storing the negative tag settings on the same tag name prefixed with '!'. Then, when we apply the tag settings to the systems, we first add the tags !x to the system if they're not tagged with x.

Checklist

• Self-review changes.
• Evaluate impact on the documentation.
• Ensure test coverage.
• Write new samples. (I don't think this deserves a sample of its own)

Thanks for reviewing this @fallenatlas! Honestly I'm not sure if we should merge this as it is right now.
Since @joaomanita is working on the dispatcher right now and we will have to make big changes to its structure anyway, it probably makes more sense to rethink this later. Marking this as stale and leaving it here, as it might still be useful.
