[llvm] [SystemZ] Add pass initialization for `CopyPhysRegs` pass (PR #132912)

[Dominik Steenken via llvm-commits]

https://github.com/dominik-steenken created https://github.com/llvm/llvm-project/pull/132912

This commit adds an initialization to `SystemZTargetMachine` for the `SystemZCopyPhysRegs` pass that was thus far  missing. This will enable, e.g., to run tests for that pass via `llc --run-pass=systemz-copy-physregs`.
