Add controlled collapsible component

[yigiterdev]

Currently, the open prop in the Collapsible component does not work due to its expanded state. I thought about refactoring the component for this, but this might require refactoring on the wallet-webapp side. I added the ControlledCollapsible component instead. We need this on the builder side because we want to be able to close and open the component from outside, other than clicking. @corbanbrook

Generally i think its bad to mix controlled and uncontrolled values, but after thinking about this a bit more, the collapsible really just has a single property we need to control, the open boolean. It might makes things a lot simpler to just make the Collapsible component work in both ways.

Oh... and i don't think this would introduce any breaking changes.

Simply we should check if the passed in open property was present, ie. not undefined, and then use the controlled value or use state value.

What do you think?

Yeah makes sense. I fixed it as you suggested. I hope I understood correctly, it should work better this way. @corbanbrook
