Peter Marshall da66158fe1 [platform] Implement delayed tasks in the default worker runner
This was unimplemented but is needed for Perfetto which posts delayed
tasks on worker threads e.g. drain the trace buffer into a file every x
seconds.

This is implemented by adding a second queue which holds the delayed
tasks in chronological order of 'next-to-execute'. We use an
std::multimap for the queue so that we can easily get the next delayed
task with begin().

The implementation will move delayed tasks into the main task queue
when their deadline expires.

Drive-by cleanup of the runner destructor which can just use = default.
