RFR: 8319242: HotSpot Style Guide should discourage non-local variables with non-trivial initialization or destruction [v2]

[Kim Barrett]

> Please review this change to the HotSpot Style Guide to add discussion of how
> we prefer to handle initialization and destruction of non-local variables.
> 
> I propose this is an editorial change, as it just documents current practice
> rather than suggesting a change to current practice. As such, the normal
> HotSpot PR process applies.
> 
> The updated .html file was generated using make update-build-docs.
