Writing multidimensional views is broken on v1.5

[jipolanco]

It seems like #36405, included in Julia 1.5-rc1, broke write for multidimensional SubArrays:

julia> x = rand(10, 10);

julia> v = @view x[1:3, 1:3];

julia> write(stdout, v)
ERROR: MethodError: no method matching pointer(::SubArray{Float64,2,Array{Float64,2},Tuple{UnitRange{Int64},UnitRange{Int64}},false}, ::Tuple{Int64,Int64})
Closest candidates are:
  pointer(::AbstractArray{T,N} where N) where T at abstractarray.jl:1002
  pointer(::AbstractArray{T,N} where N, ::Integer) where T at abstractarray.jl:1003
Stacktrace:
 [1] write(::Base.TTY, ::SubArray{Float64,2,Array{Float64,2},Tuple{UnitRange{Int64},UnitRange{Int64}},false}) at ./io.jl:666
 [2] top-level scope at REPL[25]:1

This works as expected on Julia 1.4.2.

The problem is in the write function for SubArray, which calls pointer(::SubArray, ::Tuple{Vararg{Int}}) with a tuple of indices. This variant of pointer was removed in #36405.
