ui: Include one or more perf tracks in area selection. - factor out some of the code in aggregation_controller, so that it can be reused in flamegraph_controller; - if area selection changes, call the flamegraph_controller; - modify FlamegraphState, so it can contain start timestamp, end timestamp and array of upids; - in FlamegraphDetails, store a boolean indicating if the area has changed. Examples: a)select part of a perf sample: https://screenshot.googleplex.com/8TGQYTadUscnTUt b)select perf samples across multiple processes: https://screenshot.googleplex.com/3HgpSSQPGRMzjVw Bug: b/195934783 Change-Id: I2d17b10eb997b37f6d0268f04530314b1aacb11a
