[llvm-mca] Track cycles contributed by resources that are in a 'Super' relationship.

This is required if we want to correctly match the behavior of method
SubtargetEmitter::ExpandProcResource() in Tablegen. When computing the set of
"consumed" processor resources and resource cycles, the logic in
ExpandProcResource() doesn't update the number of resource cycles contributed by
a "Super" resource to a group.  We need to take this into account when a model
declares a processor resource which is part of a 'processor resource group', and
it is also used as the "Super" of other resources.
