RFR: JDK-8349077 : Rename GenerationCounters::update_all [v3]

[Suchismith Roy]

> JBS Issue : [JDK-8349077](https://bugs.openjdk.org/browse/JDK-8349077)
> 
> we found the method names update_all of the class GenerationCounters and its subclasses are not so good. It is better to rename it to something like update_capacity (such as ZGenerationCounters::update_capacity).
> 
> 
> 
> Update_capacity exists, since update_all updates the size and used , I found update_memory_state as a better name for this method.
