Fix T65670: bone envelope head radius missing from transform panel

Make the transforms section of the properties panel consistent with
the transforms section of the side-bar, and to expose some currently
hidden BBone properties in the Bendy Bone section.

- Object transformations were not consistent with Pose Bone
transformations in that they did not use single-column layout.

- Even in Pose Bone transformations,
the rotation mode option was after Scale.

- Edit Bone Transforms panel included "Tail Radius" and
"Envelope Deform Distance", neither of which belong there. See T65670.

- Expose bbone_x and bbone_z.
