Add option to toggle console window on Windows

This is an editor setting and its value can also be toggled
using an entry in the Editor toolbar. The console will still
appear briefly when starting the project manager or editor,
as it's still compiled as console application.

Does not impact exported games, which will still run without
console in release and with console in debug mode.

A project setting or export option could be added to disable
it in debug mode if there's demand for it, but that would
greatly reduce the usefulness of debug builds if Windows users
can no longer report error and crash messages.

Fixes #17889.
