Enable maximized gl components

[MichaelBuessemeyer]

This PR enables the maximize functionality of golden layout. The changes are kept to a minimum by only changing CSS properties. Except for the maximized item, the items must be hidden (this includes the header of a golden layout component). To perform this the content of the page is directly edited via the DOM interface.

known issues

• The 3d viewport does not render correctly when maximized, as the other viewports are not rendered.
• After resuming from the maximized version the 3d Viewport is broken.

URL of deployed dev instance (used for testing):

• https://enablemaximizedglcomponents.webknossos.xyz

Steps to test:

• open any kind of tracing view.
• arrange the components of the view freely.
• maximize one component by using the maximize icon in on the right side of the header of a component.
• If a stack is maximized, changing tabs should work out and should not close the maximized view.
• There should not be any borders or headers of "hidden" components visible.
• leaving the maximized view should work out fine and the layout should be the same as before.
• The maximized state should be saved, when reloading (assuming the layout was saved via auto save or manually)

Issues:

• fixes Enable maximize option in golden layout #3743

Very nice 👍 Feels really good!

The 3d viewport does not render correctly when maximized, as the other viewports are not rendered.

I think, this is alright. It's not a bug per se, in my opinion, but only a logical consequence from the design choices we made.

After resuming from the maximized version the 3d Viewport is broken.

This is probably strongly related to the other issues with the 3d viewport, right? Or is this the bug you created another issue for which already exists on master?

Awesome!

Please don't forget to update the changelog before merging.
