More Annotation Tool functionality - Move

Allow movement of annotations after they are drawn.

either:

• whole layer
• single strokes
• stroke stroke selection/ groups

This would be especcially usefull in editors like shader editor or geometry nodes , where annotations can help a lot with complex node-setups. At the moment it doesn't because changes in the node tree can't be updated in the annotations without erasing and redrawing them.

optional workaround: frames and text - but this isn't quite the same and less intuitive.
