Don't allocate way too much memory in wxVector::reserve().

We multiplied the number of items by the size of each element twice, once in
wxVector::reserve() itself and once in Ops::Realloc() it called, so we
allocated much more memory than actually needed.

Fix this by passing the number of elements to Ops::Realloc().

Fix swapping items client data in wxEditableListBox.

Use wxUIntPtr, not long, and SetItemPtrData() instead of SetItemData(), to
ensure that we preserve the values of client data pointers in 64 bit build,
otherwise they were truncated to 32 bits.

Closes #15687.
