Add preview for cycle tabs (Ctrl-Tab)

Linked request on Github: https://github.com/brave/brave-browser/issues/33693

Description

Add a preview overlay when cycling through tabs using the Ctrl-Tab shortcut, the same way Firefox does.

This is a live changer when you work with several tabs. It is the equivalent of window switching on most OSes but in this case for tabs.

Firefox has this feature at least a decade ago, and I’m truly missing it, and would love to see it on Brave :slight_smile:

This would be huge, legit can’t use the recent tab cycling without this. Arc is also a good example of a way this is well executed
