LoopVectorization fails with Tullio and HybridArrays

Please see this issue,

Minimal reproducer:

julia> using ArrayInterface, HybridArrays

julia> d1 = HybridMatrix{3,StaticArrays.Dynamic()}(rand(3,100));

julia> ArrayInterface.dense_dims(d1)

julia> ArrayInterface.dense_dims(d1.data)
(static(true), static(true))

It should not return nothing.

Either HybridArrays should support ArrayInterface, or you should add an ArrayInterfaceHybridArrays to https://github.com/JuliaArrays/ArrayInterface.jl/tree/master/lib.

Seems dense_dims is missing from https://github.com/JuliaArrays/HybridArrays.jl/blob/master/src/array_interface_compat.jl
