Currently, when a debugger injects a call, that call happens on the goroutine where the debugger injected it. However, this requires significant runtime complexity that we're about to remove. To prepare for this, this CL switches to a different approach that leaves the interrupted goroutine parked and runs the debug call on a new goroutine. When the debug call returns, it resumes the original goroutine. This should be essentially transparent to debuggers. It follows the exact same call injection protocol and ensures the whole protocol executes indivisibly on a single OS thread. The only difference is that the current G and stack now change part way through the protocol. For #36365.
