binutils-unwrapped-all-targets: init at 2.38

It's not exactly a new package: binutils has been exposing
`withAllTargets = true;` knob for a while.

To give it more official status let's expose it as an
`binutils-unwrapped-all-targets` attribute.

Note that `binutils-unwrapped.override { withAllTargets = true; }`
does not work due to recursive definition of binutils.

Closes: https://github.com/NixOS/nixpkgs/issues/82792
