Remove myself as owner of clang-query.

[pcc]

Summary

I haven't been involved with the project for years, so it's probably
best for someone else to be the code owner.

Thank you for all of your hard work on clang-query!

I'm happy to pick up the torch as I seem to do a fair amount of the reviews for the tool, but I'm also happy to let Manuel or Alex pick it up if they would prefer.

I'll go ahead and add myself as code owner. Peter can remove himself at his leisure.
