Libs roadmap

[assambar]

Is your feature request related to a problem? Please describe.

Raw list of things we want to do about the published reusable common libs (not in order):

• [ ] Polish and integrate the intermal wasmedge_sock library into php-8.2.0
• [ ] Writeup a wlr_context library that extracts the common asyncify-based setjmp/longjmp code used by Ruby.
• [ ] Use wlr_context in php-8.2.0
• [ ] Find a curated list of next libraries to patch
• [ ] Add an autoconf based example in libs/examples (we only got a CMake based one now)
• [ ] Document all used dependencies with a release asset
• [x] Add packaging of libpython as part of the python build
