[llvm-mca] Rename Backend to Pipeline. NFC.
Summary:
This change renames the Backend and BackendPrinter to Pipeline and PipelinePrinter respectively.
Variables and comments have also been updated to reflect this change.
The reason for this rename, is to be slightly more correct about what MCA is modeling. MCA models a Pipeline, which implies some logical sequence of stages.
