Gravitational potential energy is energy an object possesses because of its position in a gravitational field. Huh ! Catch 22 ! We are back to gravity and where does it come from. What is it ? The base question of this thread.
Inert masses are incapable of exerting or generating energy. Back to the drawing board.

Yes, they obtained the potential energy when they exploded away from each other from the big bang. The field is always there and the energy came from the same place all energy comes from (whereever that is, don't ask me it's a mystery). Classically energy isn't a "thing" it's "the capacity to do work", the inert object has the potential (given how gravity works) to crash into another therefore it has potential energy.
If what you are looking for is a complete ontological description of gravity and/or energy I'm afraid that will never be coming.
