[llvm] [llvm-mca] Account for AcquireAtCycles in llvm-mca (PR #80742)

Thank you for the patch @michaelmaitland! When talking about the AcquireAtCYcle/ReleaseAtCycle change with @adibiagio , he mentioned that llvm-mca needed updating to account for this.

Unfortunately I do now know enough about LLVM-MCA to be able to tell whether what you are doing is correct or not.

What puzzles me are the changes in the tests, because I was expecting a NFC for the rework.

I kindly ask you to seek @adibiagio feedback for moving forward.
