Add Elevation Controller for filtering vertical data in 2d maps

PR Description:

This is the equivalent of the temporal controller, but for elevation z-range slicing of data in 2d maps. It's accessed through a new "Data Filtering" submenu in the View menu (in which I've also added Temporal Controller, since that was previously not accessible via menus).

The controller shows as a range slider on the left of the map. There's a configure action for setting the project's elevation range, which dictates the range available from the widget.

This works for all map layers which respect qgis/QGIS-Enhancement-Proposals#201, which are currently point clouds and raster DEMs.
