Add cookie consent notice blocking P3A metrics

[DJAndries]

Description

Add two P3A questions for cookie consent notice blocking settings.

"If you have viewed the cookie consent block prompt, how did you react?" Brave.Shields.CookieListPrompt

0) Have not seen the prompt 1) Have seen the prompt, but did not react 2) Clicked "No thanks" on the prompt 3) Clicked "Block cookie notices" on the prompt

"Do you have cookie consent notice blocking enabled?" Brave.Shields.CookieListEnabled

0) No 1) Yes

The above requires 1.45.104 or higher for 1.45.x verification 👍

Labelling as QA/Blocked as we'll need to wait for https://github.com/brave/brave-browser/issues/26078 to be fixed and uplifted into 1.45.x. We'll also need to enable BraveAdblockCookieListOptInStudy on BETA and Release before we can verify the above as we'll be enabling this feature via Grffin on both Desktop & Android.

@Uni-verse @srirambv I can run through this as I have the most context/been working on this for a while.
