Add <input type=checkbox switch> macOS implementation

https://bugs.webkit.org/show_bug.cgi?id=263372
rdar://117199685

Reviewed by Aditya Keerthi.

Add a macOS implementation that has these known shortcomings:

- There's no animation support.
- There's no focus support.
- There's no support for dragging the thumb.

Also correct an issue with m_hasSwitchAttribute invalidation. An early
return could be triggered when modifying the control through Web
Inspector which then resulted in the state not being updated correctly.

This builds on excellent prototyping work done by Lily Spiniolas. And
also greatly benefited from the advice and guidance of Aditya, Elika,
and Wenson.

Tests have been added in 270176@main and tests added here are upstreamed
via web-platform-tests/wpt#42945.
