IgxGridSelectionService.generateRange crashes on drag-select released outside grid

[MonikaKirkova]

Description

IgxGridSelectionService.generateRange throws when state.node is null. This occurs when a keyboard navigation event fires during an active pointer drag-select, which calls initPointerState() and nulls pointerState.node. If the pointer is then released outside the grid, pointerOriginHandler invokes pointerUp → generateRange(node, this.pointerState), which destructures state.node without a null check.
