DPL: Fix leaks and self-assignment in Array2D - #15938
Merged

Conversation
The copy and move assignment operators overwrote the data pointer without releasing the previous buffer, leaking it on every assignment to a non-empty array Copy self-assignment also allocated the new buffer before reading from the source, so the array was filled from its own uninitialised memory. Now guards against self-assignment and releases the old buffer.
