Utilities rename

[maloel]

• Rename utilities -> rsutils (project, paths, namespaces)
• Pyrsutils now shows with this name and not utilities-py
• Rename librealsense::to_string() (out of types.h) and rs2::to_string() (out of rendering.h) and move into rsutils::string::from()
• Python libs now go under Library/Python (they were intermingled with the other libraries under Library)

concurrency.h in not inside a namespace.
Can you add an rsutils namespace for it?

[Nir-Az]

chrono.h is also without a namspace, is that on purpose?
Doesn't it possible that it will interfere with users code?

[Nir-Az]

We have 2 time classes?

[maloel]

Not two classes.
We had one namespace, and the stuff in common/ added to it.
I didn't touch common/, so it stayed in the utilities namespace, while the stuff in rsutils moved.
common/ adds device-specific (L500 mainly) logic, which doesn't belong in rsutils.

[Nir-Az]

OK.. I must say it's confusing.

I can and I will.
You want it all in one PR?

This is on purpose, at least in part -- here we need to override global mechanisms. Still, I'll take a look later.
