examples/*-winit-wgpu: make less verbose
This updates the *-winit-wgpu examples to use `log::info!` instead of `trace!` and sets the log level to `Info` The examples now also print info about and Winit Window events. This makes them more practical to use to see how Winit events are delivered without lots of tracing spam from dependency crates.
