Adds a new re_renderer example to make it easier to look at depth offset and general depth precision issue. Example description in the comments.

Mitigates depth offset issues by blowing up the depth offset by a large value and moving the near plane closer. Tested this with:

  • objectron, 3d points added to 2d scene
  • arkit, all objects added to 3d scene and step wise removed
  • native api_demo to check on depth offset example (this failed before!)

Independently, did a fix for cargo run-wasm --build-only to have it not spawn a browser window.

... just noticed that zooming in in the api_demo depth offset demo still causes flickering 🤦

given that the hover preview also flickers this might have a different reason though!
