Add and use BitmapHeapScanDescData struct Move the several members of HeapScanDescData which are specific to Bitmap Heap Scans into a new struct, BitmapHeapScanDescData, which inherits from HeapScanDescData.
This reduces the size of the HeapScanDescData for other types of scans and will allow us to add additional bitmap heap scan-specific members in the future without fear of bloating the HeapScanDescData.
