Port Bisq 2 version of the Webcam integration to Bisq 1

[HenrikJannsen]

In Bisq 2 we added support for webcam by starting a new java process for the webcam app to reduce risks from the many dependencies on native libs we introduce with the webcam support.
This model worked well but requires some support from the build system.
We should port that Bisq 2 model over to Bisq 1 as well. It might require minimal code changes from the use of some common lib code, but those changes should be trivial.
