Postpone interrupts while dipatching debugger events to listeners

Postpone interrupts while dipatching debugger events to listeners

The interrupts are already postponed in message handlers [1]. This CL aligns debug event listener (the mechanism that is actually used in Chrome DevTools) implementation with that. Handling interrupts on events like v8::AfterCompile leads to crashes like the one in the lined bug. This happens because in the interrupt handler we may change debugger state.

Yang, please take a look.

In next CL I'm going to extract common code from
OnBeforeCompile/OnAfrerCompile/OnCompileError. There is too much duplication at
the moment.
