runtime: consolidate all trigger-derived computations Currently, the computations that derive controls from the GC trigger are spread across several parts of the mark termination code. Consolidate computing the absolute trigger, the heap goal, and sweep pacing into a single function called at the end of mark termination. Unlike the code being consolidated, this has to be more careful about negative gcpercent. Many of the consolidated code paths simply didn't execute if GC was off. This is a step toward being able to change the GC trigger ratio in the middle of concurrent sweeping and marking. For this commit, we try to stick close to the original structure of the code that's being consolidated, so it doesn't yet support mid-cycle adjustments. For #19076.
