[Dashboard][Collapsable Panels] Allow dragging between sections with touch events

[Heenawter]

Describe the bug:

While touch events now work in kbn-grid-layout, there is a known bug with dragging between sections as described here:

kibana/packages/kbn-grid-layout/grid/use_grid_layout_events.ts

Lines 133 to 135 in 37d7a5e

	// TODO: a temporary workaround for the issue where the panel moves to a different row when the user uses touch events.
	// Touch events don't work properly when the DOM element is removed and replaced (which is how we handle moving to another row) so we blocked the ability to move panels to another row.
	// Reference: https://stackoverflow.com/questions/33298828/touch-move-event-dont-fire-after-touch-start-target-is-removed

To prevent the bug, we blocked panels from being dragged between sections when using touch events - however, we should address this before we add collapsable sections to Dashboard because blocking behaviour like this with no explanation is not good UX.
