RFR: 8189685: need PerfMemory class update and a volatile_static_field support in VMStructs [v4]

[Chris Plummer]

> During [JDK-8151815](https://bugs.openjdk.org/browse/JDK-8151815) it was noted that the PerfMemory _initialized and _destroyed fields should be volatile, but VMStructs didn't have the needed support for doing that, so it was left as a future task. @YaSuenag provided a patch at the time to take care of the VMStructs support. I've integrated it, although it was far from clean due to some changes in VMStructs, and also moving OrderAccess::release_store to Atomic::release_store.
> 
> One other change I made to the patch had to do with consistency with using "volatile static" vs "static volatile". We already have volatile_nonstatic_field. The patch renamed static_ptr_volatile_field to static_volatile_field to make it more general purpose, but this was inconsistent with the name of volatile_nonstatic_field, so I chose the name volatile_static_field instead. This carried over into some other areas like the names of the GENERATE_VOLATILE_STATIC_VM_STRUCT_ENTRY and CHECK_VOLATILE_STATIC_VM_STRUCT_ENTRY macros.
