target: mbedos5: Add return value to setTimeout/setInterval and implement clearTimeout/clearInterval (#1457)

Browse Source 
In the mbedos5 target the setTimeout and setInterval functions are not on spec, as they return 'undefined' instead of an event ID. Also clearTimeout and clearInterval are not implemented, so scheduled events cannot be canceled. This patch changes the behavior of the set* functions, and implements clear* functions.
