[MC] Move the instruction latency computation from TargetSchedModel to MCSchedModel.
The goal is to make the latency information accessible through the MCSchedModel
interface. This is particularly important for tools like llvm-mca that only have
access to the MCSchedModel API.
This partially fixes PR36676.
No functional change intended.
