This CL improves the stack traces that accompany exceptions. Whenever an async function is entered, we remember how we got there. This is similar in spirit to package:stack_trace but the implementation is more efficient and memory usage can be more easily reasoned about. Tracking causal stack traces: - [x] Upon entry to an async function, capture the synchronous stack trace prefix and store it into the closure. - [x] Upon entry to an async* function, capture the synchronous stack trace prefix and store it into the closure. - [x] Before returning from an async function, clear the Thread's asynchronous stack trace. - [x] After resuming an async function, load the sychronous stack trace prefix into the Thread. - [x] Filter stack traces to remove async machinery. Service protocol changes: - [x] Send causal async stack trace. Observatory changes: - [x] Display causal async stack trace below async functions.
