Add a freecam camera controller example #21467
Description
What problem does this solve or what need does it fill?
This is a nice feature, and doesn't have an example to demonstrate it!
What solution would you like?
Add an example with a simple scene, and a way to adjust the various camera properties.
Cleanly split the scene spawning from the editor cam from the camera twiddling; probably by using modules + plugins. This makes it easier for folks to grab only the bits that they want.
What alternatives have you considered?
We could wait for a first-party entity inspector, and use that to control the camera properties.
