[llvm] [CodeGen][NewPM] Improve start/stop pass error message CodeGenPassBuilder (PR #102591)

[Akshat Oke via llvm-commits]

https://github.com/Akshat-Oke created https://github.com/llvm/llvm-project/pull/102591

Remove the pass-name-to-class-name lookup because it does not exist (that's why this error is thrown). Print the name given as the option instead.
