Add ability to spawn Windows process with Proc Thread Attributes | Take 2

This is the second attempt to merge pull request #88193 into the standard library.

This PR implements the ability to add arbitrary attributes to a command on Windows targets using a new `raw_attribute` method on the [`CommandExt`](https://doc.rust-lang.org/stable/std/os/windows/process/trait.CommandExt.html) trait.

`@TyPR124` and my main motivation behind adding this feature is to enable the support of pseudo terminals in the std library, but there are many more applications. A good starting point to get into this topic is to head over to the [`Win32 API documentation`](https://learn.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-updateprocthreadattribute).
