Removes redundant "Zoom In/Out" entries in the View menu

As discussed in #1471, we already have the zoom buttons in the bottom right corner, so having those in the menu just adds clutter, instead of actually presenting new menu options.

I was thinking how to rework the View panel menu, cause View icons aren't that common in raster editors, comparing to Edit / Effects / Adjustment etc, so I was thinking of something like that (pardon the crude mockup):

I was thinking whether we could have the View options right next to the zoom icon in the bottom of the screen, as it also pertains to zooming in/out and feels more compartmentalized (I went with the More... three-dot option icon).

One thing to be careful about is that the Show/Hide option lets you hide the status bar, so if the menu moves there you could end up in a state where you can't get the status bar back :)
That section, and the color scheme, also are more application-level settings that feel like they should be more in a "main" menu IMO

I had that idea at the start, but the view menu shows more than just zoom levels (which we just removed half of the items in this Merge Request), so I believe it's more adequate to keep it at the top, as it is currently.
