os::net: expanding TcpStreamExt for Linux with `tcp_deferaccept`.
allows for socket to process only when there is data to process, the option sets a number of seconds until the data is ready.

Always use WaitOnAddress on Win10+
`WaitOnAddress` and `WakeByAddressSingle` are always available since Windows 8 so they can now be used without needing to delay load. I've also moved the Windows 7 thread parking fallbacks into a separate sub-module.

Fix sgx unit test compilation
Fixes a compilation error:
```
error[E0583]: file not found for module `tests`
--> library/std/src/sys/locks/rwlock/sgx.rs:2:1
|
2 | mod tests;
| ^^^^^^^^^^
|
= help: to create the module `tests`, create file "library/std/src/sys/locks/rwlock/sgx/tests.rs" or "library/std/src/sys/locks/rwlock/sgx/tests/mod.rs"
= note: if there is a `mod tests` elsewhere in the crate already, import it with `use crate::...` instead
For more information about this error, try `rustc --explain E0583`.
error: could not compile `std` (lib test) due to 1 previous error`
```
When running command:
```
`TF_BUILD=True RUST_TEST_THREADS=1 ./x.py test --stage 1 "library/std" tests/assembly tests/run-make --target=x86_64-fortanix-unknown-sgx --no-doc --exclude src/tools/linkchecker --exclude src/tools/rust-demangler --no-fail-fast 2>&1
```
The fix is done by moving a file to the location suggested by the compiler.
The issue was introduced by PR: https://github.com/rust-lang/rust/pull/121177

Currently all architecture-specific memchr code is only used in
`std::io`. Most of the actual `memchr` capacity exposed to the user
through the slice API is instead implemented in core::slice::memchr.
Hence this commit deletes memchr from std::sys[_common] and replace
calls to it by calls to core::slice::memchr functions. This deletes
(r)memchr from the list of symbols linked to libc.

Reduce monomorphisation bloat in small_c_string
This is a code path usually next to an FFI call, so taking the `dyn` slowdown for the 1159 llvm-line (fat lto, codegen-units 1, release build) drop in my testing program [t2fanrd](https://github.com/GnomedDev/t2fanrd) is worth it imo.

Move `OsStr::slice_encoded_bytes` validation to platform modules
This delegates OS string slicing (`OsStr::slice_encoded_bytes`) validation to the underlying platform implementation. For now that results in increased performance and better error messages on Windows without any changes to semantics. In the future we may want to provide different semantics for different platforms.
The existing implementation is still used on Unix and most other platforms and is now optimized a little better.

Use a hardcoded constant instead of calling OpenProcessToken.
Now that Win 7 support is dropped, we can resurrect #90144.
GetCurrentProcessToken is defined in processthreadsapi.h as:
FORCEINLINE
HANDLE
GetCurrentProcessToken (
VOID
)
{
return (HANDLE)(LONG_PTR) -4;
}
Since it's very unlikely that this constant will ever change, let's just use it instead of making calls to get the same information.

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

up to now, it had been assumed the stack guard setting default is not touched in the field but some user might just want to disable it or increase it. checking it once at runtime should be enough.

Make contributing to windows bindings easier
This PR does three things:
- Automatically sorts bindings so contributors don't have to. I should have done this to begin with but was lazy.
- Renames `windows_sys.lst` to `bindings.txt`. This [matches the windows-rs repository](https://github.com/microsoft/windows-rs/blob/8e71051ea8a57594478e585d2740126893f9dbb7/crates/tools/sys/bindings.txt) (and repos that copy it). I believe consistency with other projects helps get people orientated.
- Adds a `README.md` file explaining what this is about and how to add bindings. This has the benefit of being directly editable and it's rendered when viewed online. Also people are understandably jumping right into the `windows_sys.rs` file via ripgrep or github search and so missing that it's generated. A `README.md` alongside it is at least slightly more obvious in that case. There is still a small note at the top of `windows_sys` in case people do read from the beginning.
None of this has any impact on the actual code generated. It's purely to make the new contributors workflow a bit nicer.
