UI: Only hide locked transform manipulator axes for matching spaces

The manipulator would hide axes that were locked, even if the lock was
applied to a different space. That would lead to confusing behavior of
the manipulator. E.g.:
* Add armature
* Enter Pose Mode and select the bone
* Lock X and Y location in the Sidebar
* Enable the Move tool
* Only the Y axis is visible, but doesn't do anything on dragging
The manipulator would only show the Y axes, even though the lock is
applied to the bone's local Y axis, which matches the manipulators Z
axis.
