RFR: 8351146: JFR: JavaMonitorInflate event should default to no threshold and be disabled [v2]

[Aleksey Shipilev]

> There is a threshold for inflate event. But the operation that is covered by that event is very fast, and often lock-free, so the threshold would filter many events. This would be important as we add deflation event ([JDK-8351142](https://bugs.openjdk.org/browse/JDK-8351142)), which should match inflations.
> 
> The only way I see this event be longer than default threshold of 10ms is transiently waiting for another thread to complete inflation.
> 
> Additional testing:
>  - [x] Linux x86_64 server fastdebug, `jdk_jfr` still passes
