Put 'Pause Preview' button else where

When you work with heavy scene, it takes some time to change between 'Viewport Shading' mode.

I click the button several times when my shading mode doesn't change right away.

After the shading mode changed to/from 'Rendered', every button moved as the menu layout has changed due to 'Pause Preview' button suddenly appears or disappears.

Then I got an unwanted button clicked like 'Toggle X-Ray' or 'Material Preview' shading button.

I think it is a bad UX. Let's put 'Pause Preview' button somewhere more sensible.
