RFR: 8340334: Update jcmd VM.events max parameter to be INT [v2]

[Leonid Mesnik]

> The  jcmd VM.events max parameter type is changed to INT.
> Also,I noted the max <= 0 is ignored, so I updated documentation and set "0" as a default value.
> The jcmd exists if parameter is negative now.
> 
> The `max` is `int` while really it is the unsigned int. However I don't think it makes sense to change it to `size_t` or `unsigned int` in all places where 'max' is used.
