Title: HPCC-8017 Expand huge allocations into adjacent free blocks on resizeRow

Calls to resizeRow for a huge (>1Mb) memory block will expand the currently
allocated block where possible, rather than always creating a new one and
copying into it.

This can have a significant impact on the fragmentation of the roxiemem
heap.
