Photo Capture Web component

[timea-solid]

We have an old v2 PhotoCapture component which is linked in the new ones and used in profile-pane.
In order to delete the v2 code we need a proper Web Component.

I just created a stack PR addressing this issue in NoelDeMartin#1. There are more things that could be done to modernize this component, such as using the InputTrait or the new Dialog system. But for now I've only migrated the location and using the new decorators. Depending on the priority, we could create a follow-up issue or address those other concerns here in this one. I'm moving it to "in review" for now, until we decide.

You can go ahead and use the Traits and the new dialog if it fits.
