Copying contents of a segments into an array (or viceversa) is currently convoluted as users have to convert the array into a segment, and then slice source/dest segment and perform a bulk copy using copyFrom.

We could add static helpers on MemoryAccess, like these:

@ForceInline
    public static void getToIntArray(MemorySegment segment, long srcIndex, int[] arr, int dstIndex, int nElems) {
        MemorySegment srcSegSlice = segment.asSlice(srcIndex << 2, nElems << 2);
        MemorySegment dstSeg = MemorySegment.ofArray(arr);
        MemorySegment dstSegSlice = dstSeg.asSlice(dstIndex << 2, nElems << 2);
        dstSegSlice.copyFrom(srcSegSlice);
    }

Which will greatly simplify the task. The dual of this could be called "setFromIntArray".

Note that maybe we'd want AtIndex/AtOffset variants (to specify segment position in logical index vs. raw offset), plus endianness (e.g. to do a "swappy" bulk copy), which makes for 4 overloads per carrier type, per accessor type (get/set).
