cookie consent modal/notification should close when switching/losing or opening NTP

[kjozwiak]

Description

As per the desktop implementation of the Cookie Consent feature, we should ensure that it dismisses/closes in the following cases:

* The user switches tabs
* The user closes the active tab
* The user opens a new tab

Once #25811 was fixed, it made it so the user couldn't dismiss the notification/modal without making a decision but didn't take the above cases into consideration. As per @pes10k, we should get this into 1.45.x so when we enable the BraveAdblockCookieListOptInStudy, it will work as expected on 1.45.x.

Steps to reproduce

1. download/install Brave Nightly
2. open any random website
3. refresh the same website ~5 times (the cookie consent should appear after the 5th refresh)
4. once it's visible, don't make a decision and start creating new tabs/switching tabs

You'll notice that the cookie consent notification/modal isn't being dismissed.

The above requires 1.45.109 or higher for 1.45.x verification 👍
