Implement Into<ArrayData> for T: Array

[tustvold]

Is your feature request related to a problem or challenge? Please describe what you are trying to do.

The array implementations are just strongly typed wrappers around an ArrayData. It therefore makes sense that the conversion can be performed cheaply. Currently the only way to do this uses Array::data and ArrayData::clone, the latter of which is not especially cheap.

Describe the solution you'd like

I would like all T: Array to impl Into<ArrayData>. Additionally these implementations should provide an into_data member function to aid in type inference.

fn into_data(self) -> ArrayData {
  self.into()
}

Describe alternatives you've considered

We could not do this, but it is fairly common to see array.data().clone() which just seems unnecessary
