Revert resized canvas and don't render resize handles when zoomed out

[t-hamano]

Description

Enabling zoom-out view on resizable canvases such as template parts or patterns results in unnatural scroll bars. Also, when you move the resize handle, the canvas size seems to change unnaturally.

I think if zoomed-out view is enabled, we need to revert the resized canvas size and disable the resizing feature itself.

Step-by-step reproduction instructions

• In advance, enable "Zoomed out view" on the "Experiments" page.
• Open the site editor.
• Open the pattern you created or one of the template parts.
• Click the Zoom Out View button.
• Play with the resizing handles and test how the canvas changes.

Agreed. I detailed the same in #60052. I'll close that in favor of this one.
