MUI v6

[fhammerschmidt]

I created a v6 branch.

Please submit your changes there until we have a first version out.

@illusionalsagacity you probably have some of the necessary changes lying around already?

I do have some, but admittedly we've been fine with continuing to use some of the deprecated APIs (from v5 -> v6) for the moment. The one that stands out the most is Grid2 but the binding is nearly identical if I recall correctly.

@fhammerschmidt I started working on finishing up the bindings for the slots / props, I have them mostly completed using OverridableComponent.t (the equivalent of React.ElementType in TS) and falling back to JsxDOM.domProps if there wasn't an explicit Mui component props type for them. Should they be CommonProps.t instead for sx compatibility?

I think with the props type casting from OverridableComponent it should pretty much work though.
