Performance problems when using broadcasting and logical operators

[roflmaostc]

Broadcasting with boolean operators seems to be very slow in some circumstances:

See below one example with Julia 1.8.2:

julia> x = randn((100,));

julia> y = randn((1,100));

julia> @time (x.^2 .< 1) .&& (1 .+ y.^2  .<1);
  0.004369 seconds (144.73 k allocations: 3.005 MiB)

julia> @btime ($x.^2 .< 1) .&& (1 .+ $y.^2  .<1);
  4.009 ms (144713 allocations: 3.00 MiB)

# this works
julia> @btime ($x.^2 .< 1) .&& ($y.^2  .<1);
  2.523 μs (3 allocations: 5.56 KiB)

julia> @btime ($x.^2 .< 1) .|| ($y.^2 .+ 1 .<1);
  2.738 μs (3 allocations: 5.56 KiB)

Our .&& and .|| is flatten based so I believe this is a duplication of #27988.
With #43322, I get

julia> @btime ($x.^2 .< 1) .&& (1 .+ $y.^2  .<1);
  10.400 μs (3 allocations: 5.56 KiB)

julia> @btime ($x.^2 .< 1) .& (1 .+ $y.^2  .<1);
  4.271 μs (3 allocations: 5.56 KiB)

julia> @btime ($x.^2 .< 1) .&& ($y.^2  .<1);
  10.000 μs (3 allocations: 5.56 KiB)

julia> @btime ($x.^2 .< 1) .& ($y.^2  .<1);
  4.229 μs (3 allocations: 5.56 KiB)

So perhaps .& is always a better choice here.
