Auto merge of #61005 - michaelwoerister:error-pgo-windows-unwind, r=zackmdavis
Emit error when trying to use PGO in conjunction with unwinding on Windows. This PR makes `rustc` emit an error when trying use PGO in conjunction with `-Cpanic=unwind` on Windows, isn't supported by LLVM yet. The error messages points to https://github.com/rust-lang/rust/issues/61002, which documents this known limitation.
