Currently, microbenchmark only allows you to capture one block of work, with certain portions opting out of measurement via BenchmarkRule.Scope.runWithTimingDisabled {}

Proposal is to offer a variant of measureRepeated() which allows measuring multiple sequential stages of work, especially to enable merging benchmarks of the format:

ComposeBenchmarkRule.benchmarkFirstLayout, benchmarkFirstDraw, etc.

This should save significant runtime both locally and in CI, and allow us to more clearly compare tradeoffs when moving work from one stage of UI work to another.
