Improved vertical toolbars

Currently we have a wide vertical toolbar on the left with only 3 buttons: report view, data view, model view.

A lot of useful space (especially on non ultra-wide screens) is being wasted.

Remove this toolbar.

And update the new (currently in On-Object-Interactions preview) vertical toolbar. It should include the following buttons:

[buttons to switch between views]

report view

data view

model view

[toggle buttons to show/hide panes] (list of buttons will be different in data view and model view)

Filters

Data

Selection

Bookmarks

Perf. Analyzer

Sync Slicers

[external tools]

TE3

DAX Studio

etc.
