Based on T99607:
- Existing Angle Control shortcuts are removed
- Voxel, Dyntopo and Hair resolution shortcuts are remapped to R
Since voxel remeshing is not compatible with dyntopo, each can use the shortcut R for the remeshing resolution without causing a conflict.
The shortcut R is not currently used for anything important.
The angle control menu is commonly not used.
And sculpt mode is only coincidentally inheriting the rotate operator shortcut on R because nothing else is mapped to the key.
