[foreign-memaccess] [Rev 02] RFR: Add MemorySegment::fill

> As part of feedback on the Foreign Memory API (when experimenting with
> its usage internally in the JDK), a small number of potential usability
> enhancements could be made to the API. This is the second such.
> This change proposes to add a new method:
> Which fills a value into the given memory segment. Fill can be useful to
> initialize or reset the memory of a segment, similar(ish) to memset.
> There are obviously different ways to provide such functionality, e.g.
> accepting a fill value with a bit width greater than 8 bits, but on
> balance this single method will likely satisfy the majority of simple
> use-cases. Other more advanced initialization scenarios would likely be
> served better from an interaction with the Vector API, or some such.
Chris Hegarty has updated the pull request incrementally with one additional commit since the last revision:
Make `fill` an instance method on MemortSegment.
The copy method will be renamed and moved to an instance method on segment as a follow on PR.
