Auto merge of #80290 - RalfJung:less-intrinsic-write, r=lcnr

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.

Also see [this Zulip discussion](https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/ptr.3A.3Aread.20vs.20ptr.3A.3Awrite).
