Synchronization between multiple editors

As discussed in #4850

@rlaverde, please work on this one.

I don't understand clearly what's the idea of this change, Sync all editorstacks, and move tabs in all editors is not the expected behavior, even you says that #4850 (comment)

I'm 👎 to this issue, It'll be confusing and somehow error prone, other editors doesn't sync tabs between multiple editors, neither in split view.

From a comment of @rlaverde :

Personally I'll prefer the both windows to be totally independent, not only the position of the tabs not to be synced, but also different files opened, and when closing a tab to only be closed in that window

Lets say I'm working on PR X with file 1, file 2, and file 3 opened in an Editor plugin. Now I need to work on PR Y that requires files 4, file 5, and file 6, but I don't want to close file 1, file 2 and file 3 because I will need them later. Then I need to work on another PR and so on. I usually end up with a very crowded tab bar in my editor.

One of the thing I would like is the ability to add more than one dockable editor plugin to Spyder. Each editor plugin would be completely independent from each other. The editorstacks within each editor plugin would be synced however.

@dalthviz, what was exactly this issue about? Sorry, I don't remember ;-)

@ccordoba12 I think this is related with the synchronization of the tabs to preserve the same order when opening/closing a new window. Although I'm not quite sure either.
