implement ptr::write without dedicated intrinsic This makes `ptr::write` more consistent with `ptr::write_unaligned`, `ptr::read`, `ptr::read_unaligned`, all of which are implemented in terms of `copy_nonoverlapping`. This means we can also remove `move_val_init` implementations in codegen and Miri, and its special handling in the borrow checker.
