Move visualization testing to playwright

[RaananW]

Fixes #12977

The jest vis-tests will stay as we are still using them to test WebGL1 on the CI. However, the recommended way is to use playwright. Documentation PR will follow right after this one.

Note, this is a small "breakiing change" to the repo, as now you will need to run npm run test:visualization -- --project="webgl2" to run a specific engine instead of -i webgl2.
