This commit shows how LLDB python plug-in could look like.

Such an approach allows users to use LLDB for OS kernel debugging, for doing that they only need to implement two interfaces: `OperatingSystemInterface` and `OSThread`.  As an example, this patch contains `zephyr.py` file with simple plug-in implementation for Zephyr OS, OS-specific files could live in OS' repository and evolve alongside it.

In the future, arch-specific code, e.g. `arc.py`, can be eliminated since LLDB already implements that functionality.

Remaining code can be upstreamed to LLDB with or without significant changes, the main idea of the review is to discuss these changes.
