Consistent with existing `similar` methods and the `Array` constructor, ensure
`T(::CategoricalArray{U})` and `convert(T, ::CategoricalArray{U})` return an
`Array{U}` for `T` in `Array`, `Vector`, `Matrix`. Same for `SubArray`s
of `CategoricalArray`s. This avoids creating `Array{<:CategoricalValue}`
objects which are inefficient and unlikely to be what users want.
