Adds a way to preserve user-preferred mesh grid state

[mockoocy]

Fixes a bug / bad UX in which caused mesh grid to became unhidden after certain operations like DataCollection or Phase change.

The steps to reproduce the bugs were as following:

• mount a sample
• open draw_grid control
• draw a few grids
• make some of them hidden
• right click on canvas, press Data Collection button
• run the task
  After the task was done, each of the grids was shown again.
  It's also worth adding that in the demo beamline many of the motors seem to not be mocked, so the behavior can't be observed.

The reason for this behavior was further described in this Pull request mxcube/mxcubecore#1044 for mxcubecore. This PR will be marked as draft until the mxcubecore one is merged.

The fix writes to state set by user to Shape.user_state attribute on the mxcubecore side.
When the data collection or phase change is finished, then the user-preferred state is restored by setting Shape.state to be equal to Shape.user_state.

Turns out the same issue happens for the zoom and focus controls. Will also try to fix it for these in this PR.

@mockoocy Note that there was work on focus and zoom controls very recently: #1457. I do not know if it is related or not.

added some changes;
now the UI has some indicator that specific grid is being hidden (it appears with a darker background)
I have also changed HWR.beamline.sample_view.add_shape_from_mpos function, also when updating shapes there are optionally more arguments passed to it, so that shape and user_shape are not changed when grids is being redrawn sometimes.

Thanks @mockoocy, do you happen to have a screenshot of the changes ?

@marcus-oscarsson I think we have different ideas how this mesh hidding/un-hidding is suppose to work.

Like what is the actual desired behavior. Perhaps we can discuss this in a video meeting? I'm at least a bit confused right now.

@elmjag sure, we can have a quick chat if you like. How about tomorrow ? Otherwise I think the current proposal is fine maybe the color could be a bit more fun (other than dark gray :) ) and what do you think about a text perhaps under the hide button (saying "hidden by user" and perhaps "out of view" when hidden automatically) ?
