So far, only pitch. Fuel is pumped between tanks to trim the aircraft. This is especially helpful for supersonic aircraft, because their center of pressure moves by a quarter of the wing chord between sub- and supersonic flight. The prime example would be the Concorde:
… during flight fuel is transfered from tank to tank to maintain trim
and balance of the aircraft as it does not have a full tailplane which
would be used on a subsonic airliner to perform this task. Also for
supersonic flight the Center of Gravity is critial and required to be
moved for different speeds.(source)
Before take off and during the acceleration through Mach1 to an
eventual Mach 2, fuel is pumped out of the forward trim tanks to the
rear trim tanks and the collector tanks in the wings. Around 20 tons
of fuel is moved in the process and results in a rearward shift of the
CoG by 6ft (2 meters.)

Airbus is using a similar scheme for finely adjusting the center of gravity for optimum performance.
I expect that especially for roll, fluid pumping will not give sufficiently fast response. When flying through gusty air, it is very helpful to have responsive roll control.
If you accept a solid mass rather than a fluid, then the gliders of Otto Lilienthal qualify as the first aircraft which used weight shifting for control, both in pitch and roll. Following his footsteps, every hang glider and trike is using this technique until today.
Otto Lilienthal in his Normalflugapparat, the first serially produced airplane (picture source). Here he throws his legs back in order to pitch up.
Another first used weight shifting, albeit only for pitch control: The very first Zeppelin had a 100 kg weight suspended between its fore and aft gondola which could be shifted fore and aft to adjust the center of gravity.
Pitch was controlled by a sliding weight suspended under the hull
which could be shifted fore and aft; there were no elevators for pitch
control, or fins for stability.
The weight proved insufficient, jamming on occasion of the first flight. Later is was increased to 150 kg. Elevators and fins would had helped less because the two 14 hp gasoline engines never allowed the ship to fly fast enough for effective aerodynamic control.
