e6451028c3 Use a different target function table depending on the blocking property. 
The any_executor class stores the state of the target's blocking
property to enable an optimisation in any_executor::execute(), i.e. if
the target executor has the property blocking.always, we can avoid a
memory allocation when type-erasing the submitted function object. With
this change the any_executor now "stores" the blocking property as a
different target function table, rather than as a separate member of
type blocking_t. This reduces the size of an any_executor by 8 bytes on
x86-64.

fefe9a992e Use properties to track outstanding work against an io_context. 
When using standard executors, work is tracked by requiring (or
preferring) an executor with the execution::outstanding_work.tracked
property. This replaces executor_work_guard and make_work_guard() with
code of the form

    asio::io_context io_context;
    auto work = asio::require(io_context.get_executor(),
        asio::execution::outstanding_work.tracked);

To explicitly reset work, store the returned work-tracking executor in
an any_io_executor object:

    asio::any_io_executor work
      = asio::require(io_context.get_executor(),
          asio::execution::outstanding_work.tracked);

and then assign an empty executor into the object when done:

    work = asio::any_io_executor();
