Support unfocused dimming of all workbench components like output and debug console

[bpasero]

Testing #191527

I find the choice of dimming just the terminal in the panel strange, why not dim the output pane or maybe debug console?

Let's discuss in #191610

Having talked about this in the Zurich standup, there was pushback on why only terminals and editors, but e.g. not output or debug console was included. So I am reopening this for consideration.

The plan is to add a .views: { viewId: boolean } setting but keep the default opinionated as terminals and editors, unless feedback from the community hints we should do otherwise.

@Tyriar would be awesome if we are able to control or at least when you're navigating in the sidebar with extensions like Git, GitLens you're seeing content in the editor with 1 opacity, because now it is hard to read even though I find this feature useful. But when working only with terminal & editor it is awesome, because it dims terminal and vice versa so I thought it would be cool to have view array list which should dim so we have control over this. Or maybe this will be improved in the future so that viewing search results, Git, etc. will not dim.
