llvmPackages.lldbPlugins: drop llvm/clang rebuild

Eliminate rebuilding the following packages on darwin just for this
attrset:

< DarwinTools-1.drv
< DarwinTools-1.tar.gz.drv
< IOKit-11.0.drv
< builder.pl.drv
< clang-16.0.6.drv
< clang-at-least-16-LLVMgold-path.patch.drv
< clang-darwin-An-OS-version-preprocessor-define.patch.drv
< clang-src-16.0.6.drv
< llvm-16.0.6.drv
< llvm-src-16.0.6.drv
< psutil-6.0.0.tar.gz.drv
< python3-3.12.7-env.drv
< python3.12-psutil-6.0.0.drv
< sysctl-system_cmds-1012.drv

found by diffing the output of the command below before and after this
change:
```
nix-store --query -R $(nix-instantiate -A llvmPackages.lldbPlugins) | \
  cut -d- -f 2- | sort
```
