[llvm-mca] Refactor the Scheduler interface in preparation for PR36663.
Zero latency instructions are now scheduled the same way as other instructions.
Before this patch, there was a specialzed code path for those instructions.
All scheduler events are now generated from method `scheduleInstruction()` and
from method `cycleEvent()`. This will make easier to implement a "execution
stage", and let that stage publish all the scheduler events.
No functional change intended.
