Improve dispatch of findall(testf::F, A::AbstractArray) (#46553)

This prevents some invalidations in `mightalias(A::AbstractArray, B::AbstractArray)` in abstractarray.jl when loading Static.jl. Here we specialize on the function instead of using map since `broadcasting` returns a BitArray, `map` returns a Vector{Bool}.
