In AOT the SendPort.{Send,Receive}.BinaryTree.* are really fast, because
the tree shaker will remove the fields, which will make us actually not
construct a tree at all but only one root node without fields.

Other existing benchmarks that are related (e.g. IsolateJson) measure
multiple things at the same time (e.g. utf8 decoding speed, json
decoding speed, isolate communication).
The benchmarks in this CL focus purely on sending object graphs via [SendPort]s
and measure sending and receiving time. As data we measure json
(map/list/string heavy) as well as binary trees (user object heavy).
