Always disable shadow window?

[einarf]

We've seen reports from users in 3.0.1 that simply importing arcade fails due to shadow window.

Currently we only disable shadow window on MacOS, headless and on raspi.

Traceback (most recent call last):
  File "/home/crypted/Documents/projects/makeit/test.py", line 1, in <module>
    import arcade
  File "/home/crypted/Documents/projects/makeit/venv/lib/python3.12/site-packages/arcade/__init__.py", line 98, in <module>
    from .application import MOUSE_BUTTON_LEFT

    ^^^^^^^^^^^^^^^^^^^^

                     ^^^^^^^^^^^^^^

Look out for more reports about this.

Would make sense to have a consistent experience on all platforms.
