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
