[llvm] [RemoveDIs] Update syntax highlighting to include debug records (PR #93660)

[Stephen Tozer via llvm-commits]

https://github.com/SLTozer created https://github.com/llvm/llvm-project/pull/93660

This patch updates the vim and vscode syntax highlighters to recognize debug records. I wasn't able to build the vscode extensions locally, so I've only tested this pattern by checking that the pattern works in vscode search.
