Make better use of Nx

[pascalwilbrink]

Nx is a powerful tool. We can make more use of it.

We can create a global eslint configuration with Nx (https://nx.dev/nx-api/eslint)

Acceptance criteria:

• [ ] Global eslint configuration (https://nx.dev/nx-api/eslint)
• [ ] No project specific eslint config anymore
• [ ] packages/distribution should make use of Rollup (https://nx.dev/nx-api/rollup)
• [ ] packages/core should make use of Jest (https://nx.dev/nx-api/jest)
• [ ] Check if we can simplify the NX config
