[llvm] [PowerPC] add PowerPC path for PR labeler (PR #82200)

[Chen Zheng via llvm-commits]

https://github.com/chenzheng1030 created https://github.com/llvm/llvm-project/pull/82200

Add path for PowerPC related changes to the PR labeler.

There is no `pr-subscribers-backend:PowerPC` team in the llvm org yet. Much appreciated if some admin can help to create the team.

I don't think I need to do further change to make Github automatically add the PowerPC team as the reviewers for PowerPC related PRs. The automation logic seems common for all targets.
