Add Rotate(X), Rotate(Y) and backface-visibility properties

[AbobkerElaghel]

Please add the Rotate(X), Rotate(Y) and backface-visibility properties to the library, it does help in flipping elements 180deg on the y or x axis.

I made this recently. It’s early days, but I think it has potential to fill this gap and others around 3D transforms.

A bit lacking in documentation, but should make sense to most folks familiar with Tailwind transforms.
