Support Vibrancy (Mac) and backgroundMaterial (Windows) when creating a window

[peskybogle]

To give extra app design options while remaining consistent across OS's, support for Vibrancy on Mac and backgroundMaterial (Windows) would be helpful. It adds a blur to apps with transparent or semi-transparent backgrounds so that items on the desktop or apps open behind don't distract user attention.

It's discussed here for Electron in general: https://stackoverflow.com/questions/55785565/how-do-i-blur-an-electron-browserwindow-with-transparency.

In Discord Simon said we have the Mac version supported but not documented, but don't yet have the Windows equivalent https://github.com/NativePHP/laravel/blob/main/src/Concerns/HasVibrancy.php#L30-L52

Please consider supporting on both OS's.

Any update on Windows support for this, if it's even possible? Would be nice to not have to do things a bit differently for each OS
