WIP: enhance parent_call

[johnnychen94]

• rename it to no_offset_view_apply as a part of the non-exported API.
• allow multiple inputs

I find this pattern used very widely when dealing with CUDA.CuArray,

julia> A = OffsetArray(CUDA.rand(4, 4), -1, -1);

julia> B = OffsetArray(CUDA.rand(4, 4), -1, -1);

julia> A .- B
ERROR: Scalar indexing is disallowed.

julia> no_offset_view_apply(A, B) do x, y
    x .- y
end # 🎉 
4×4 OffsetArray(::CuArray{Float32, 2}, 0:3, 0:3) with eltype Float32 with indices 0:3×0:3:

A lot of seemingly ambiguous operations can be supported by this, e.g., #93, #137
