UI: Add Missing UV Unwrap Operators to UV Editor

This commit also changes the U shortcut to open the unwrap menu instead 
of the Unwrap operator. The unwrap operator can now be accessed by 
pressing U twice.

Note, these operators use the 3D Viewports selection and not the UV 
Editor selection. In the future the operators should unwrap based on the 
selection within that editor.

Fixes T80600
