RFR: 8347408: Create an internal method handle adapter for system calls with errno [v5]

[Per Minborg]

> As we advance, converting older JDK code to use the relatively new FFM API requires system calls that can provide `errno` and the likes to explicitly allocate a MemorySegment to capture potential error states. This can lead to negative performance implications if not designed carefully and also introduces unnecessary code complexity.
> 
> Hence, this PR proposes adding a JDK internal method handle adapter that can be used to handle system calls with `errno`, `GetLastError`, and `WSAGetLastError`.
> 
> It relies on an efficient carrier-thread-local cache of memory regions to allide allocations.
