proposal to support raw_attribute with raw pointer

[cre4ture]

Hello rust community,

I'm still rather new to rust, but I collected experience with rust in the uutils project.
There I'm currently trying to make use of the conpty windows feature and stumbled across the same topic as discussion in #114854.

This was my solution to it and I found that its probably simpler as all other solutions I've seen on the discussion topic (#121951, #123604). And thus its easier to understand, use and therefor might take less discussions to get it approved.

The key element is, that I don't change the existing approach for normal data attributes with the Box::new(). I just extend the API with a second variant that takes raw pointers.

Just let me know what you think.
If there is positive feedback, I will adapt documentation and tests.

I also added a change (force_use_std_handles) that will be needed to have a proper support of the PSEUDOCONSOLE / conpty.
Its clear that this should be in a different PR. I will split it as needed after some feedback.

@Dylan-DPC thanks for the trigger.
It was a small issue with the merge. It should be fixed now. Lets see what the CI says.
I was on vacation for 4 weeks and additionally I didn't expect much attention on this PR. That's the reason for the delay.
