[vm/debugger] Simplify async breakpoints implementation

We no longer rewrite suspendable function into closures nested
inside the original function, so the whole synthetic async breakpoint
machinery is not needed.

Refactor `Breakpoint` class to make one-shot and per-closure
separate properties of breakpoint, which allows creating
one-shot-per-closure breakpoints.
