0xc0001a2040 c38659ddea Add fmt::Pointer impl for bevy_ptr::{Ptr, PtrMut, OwnedPtr} (#6980) 
# Objective

- `bevy_ptr::{Ptr, PtrMut, OwnedPtr}` wrap raw pointers and should be printable using pointer formatting.

## Solution

- Add a `core::fmt::Pointer` impl for `Ptr`, `PtrMut` and `OwnedPtr` based on the wrapped `NonNull` pointer.

---

## Changelog

- Added a `core::fmt::Pointer` impl to `Ptr`, `PtrMut` and `OwnedPtr`.

bevy_ptr

The bevy_ptr crate provides low-level abstractions for working with pointers in a more safe way than using rust's raw pointers.

Rust has lifetimed and typed references (&'a T), unlifetimed and typed references (*const T), but no lifetimed but untyped references. bevy_ptr adds them, called Ptr<'a>, PtrMut<'a> and OwningPtr<'a>. These types are lifetime-checked so can never lead to problems like use-after-frees and must always point to valid data.
