in core/alloc/std only for now, and ignoring test files
Co-authored-by: Pavel Grigorenko <GrigorenkoPV@ya.ru>

The File is unwrapped to a Handle into an AnonPipe, and then that AnonPipe was unwrapped to a Handle into another AnonPipe. The second operation is entirely redundant.

We haven't had any Windows XP targets for a long while now...

Use `std::mem::{size_of, size_of_val, align_of, align_of_val}` from the
prelude instead of importing or qualifying them.
These functions were added to all preludes in Rust 1.80.
|

Since the stabilization in #127679 has reached stage0, 1.82-beta, we can
start using `&raw` freely, and even the soft-deprecated `ptr::addr_of!`
and `ptr::addr_of_mut!` can stop allowing the unstable feature.
I intentionally did not change any documentation or tests, but the rest
of those macro uses are all now using `&raw const` or `&raw mut` in the
standard library.

The previous commit updated `rustfmt.toml` appropriately. This commit is
the outcome of running `x fmt --all` with the new formatting options.

Remove wrapper functions from c.rs
I'd like for the windows `c.rs` just to contain the basic platform definitions and not anything higher level unless absolutely necessary. So this removes some wrapper functions that weren't really necessary in any case. The functions are only used in a few places which themselves are relatively thin wrappers. The "interesting" bit is that we had an `AlertableIoFn` that abstracted over `ReadFileEx` and `WriteFileEx`. I've replaced this with a closure.
Also I removed an `#[allow(unsafe_op_in_unsafe_fn)]` while I was moving things around.

These need to get their safety story straight
|
|
Make os/windows and pal/windows default to `#![deny(unsafe_op_in_unsafe_fn)]`
This is to prevent regressions in modules that currently pass. I did also fix up a few trivial places where the module contained only one or two simple wrappers. In more complex cases we should try to ensure the `unsafe` blocks are appropriately scoped and have any appropriate safety comments.
This does not fix the windows bits of #127747 but it should help prevent regressions until that is done and also make it more obvious specifically which modules need attention.

Relaxed is enough to ensure fetch_add(1) returns each integer exactly
once.

This also keeps the old `advance` method under `advance_unchecked` name.
This makes pattern like `std::io::default_read_buf` safe to write.
