[macOS] native `DatePicker` should be implemented and be default

[KSemenenko]

Current behavior

Just add <DatePicker />

Expected behavior

The picker should look normal, without strange objects.

How to reproduce it (as minimally and precisely as possible)

Just create new project, add <DatePicker /> and run it on macOS.

Thanks for the report.

@carldebilly I think this is a duplicate of another one, right ?

Yep it's a duplicate of #5345 and mentioned in #5482.

On iOS, the default mode is to use the native picker instead of this one. But for macOS, a change is required on this line to add support for __MACOS__ native picker from the DatePicker.

Issue still present. Tested with Uno.UI 4.1.0-dev.305

This is no longer relevant as we have a new macOS backend 🚀
