Implement Qwen3-Coder

[osho]

There are several posts requesting the same.

PLeae add your votes here not only for Qwen Coder, but also for GLM4.5 and a couple other OSS models:

Qwen3-235B-A22B-Instruct and Minimax-M1

I agree that the more supported models the better! In my testing though, at least in my codebases, K2 was successful in 9/13 of my own testing methodologies and Q3C only 4/13. It works better in Cline/Roo/Kilo than in native VSC IMO. Your coding style may see totally different results as always.
