Request World Composition 2d map rotation

The default view rotation for the world composition map is set up so that Y+ is down and X is right, which is really weird and disorienting for me, i’d like to have a view option of changing the rotation to 0, 90, 180, 270 degrees, so that we can work to layout the tiles in whatever way is comfortable for us (the icon representing the coordinate system at the top left should rotate too :D).

Note that this isnt a request to be able to rotate each tile(streaming level) individually, no, this is just for overall VIEW rotation on the 2d map preview.

Wrote an initial implementation here: https://github.com/EpicGames/UnrealEngine/pull/1271
Click the x,y axis system icon to rotate the 2d view by 90 degrees ! (and right-click to go back 90 degrees)
