async_hooks,inspector: implement inspector api without async_wrap
Implementing the inspector session object as an async resource causes
unwanted context change when a breakpoint callback function is being
called. Modelling the inspector api without the AsyncWrap base class
ensures that the callback has access to the AsyncLocalStorage instance
that is active in the affected user function.

See `test-inspector-async-context-brk.js` for an illustration of the
use case.
