Replace log with tracing

Tracing is a modern replacement for the log crate that allows for
annotating log messages with the function that they come from.

Signed-off-by: John Nunley <dev@notgull.net>
Closes: #3482

 - **Breaking:** Changed the signature of `EventLoop::with_user_event` to return a builder.
 - **Breaking:** Removed `EventLoopBuilder::with_user_event`, the functionality is now available in `EventLoop::with_user_event`.
 - Add `Window::default_attributes` to get default `WindowAttributes`.
+- `log` has been replaced with `tracing`. The old behavior can be emulated by setting the `log` feature on the `tracing` crate.
