Added option for separate tab

[smartguest]

This PR adds in the requested separate tab feature similar to that of SSMS

This requires moving the functionality of the queryResultsEditor and the queryResultsView into the queryEditor itself to facilitate the layout generation more easily.

Due to the nature of how editors are created in ADS along with the layout function call, its currently only possible to change the editor layout after a restart of ADS (noted on the setting).

This PR also adds the setting to automatically switch to the results tab after a query has been run (similar to SSMS) and this does not require a restart.

@smartguest did you mean to put this in draft mode?

[smartguest]

@alanrenmsft Perhaps I should, although functionally it is complete.

[smartguest]

I need to fix the failing tests first before turning this into an actual PR

@smartguest should we close out this older PR since I think it will still need a bit of work to get merged? We can reopen later if we pick this back up.
