Using codelldb with Qt pretty printers

[ahrm]

This is a follow up to #1250. I finally figured out why codelldb doesn't work with qt pretty printers and how to fix it. The reason I am sharing this is twofold:

1. It may help others with the same problem (probably my future self!)
2. It is entirely possible (nay, likely) that I have done things in an overcomplicated and roundabout way, so if there is a better way to do it please let me know.

Turns out the issue was the Qt's python pretty printes (QtCore.py file) were using deprecated python libraries (e.g. imp) which are removed in newer python version (i.e. the python included in the codelldb distribution). So I created a modified version of QtCore.py here: https://gist.github.com/ahrm/639eae21f715d7d2c6bf3101cc667dc9 which doesn't use the deprecated libraries.

But still there was an issue because QtCore.py requires pygdbmi which is not present incodelldb's included python (and as far as I know the built-in python doesn't have an easy way of installing packages, I could be wrong about this though). So what I did was install pygdbmi on my system's python and then copy it from the system's python package location to ~/.vscode/extensions/vadimcn.vscode-lldb-1.11.5/lldb/lib/python3.12/site-packages.

It is possible, however it seems odd that it requires pygdbmi, since LLDB does not use that protocol.
