Implement cosmetic adblock filters

[bbondy]

This is partially implemented but we need to expose the support from the abp-filter-parser-cpp node module.

List of sites to check:

• reddit.com ads removed, but not replaced
• google search text ads neither removed nor replaced

Ads are appearing in brave mobile. The only way I can turn them off is to turn scripts off in the badge, which isn't a long term solution.

@bbondy Thoughts on solving via the approach in #7525? This issue feels like it may need a more robust solution.

[bbondy]

I think that's ok as a temporary thing but we want something different for the generalized approach and understanding / converting ABP filter syntax for css rules. (Most of that is already supported just not used today)

One limitation in using the manifest (presently) is that we aren't checking if the user has Replace Ads enabled. We'll want to check that before loading any styles to hide elements, or scripts to remove nodes.

I see adword ads on google search results. The first time I see them in 15 years using an adblocker in other browsers. Considering that this is your UVP, I expected better.

This seems to be a somewhat known bug but I see empty spaces on every site where the ads would be.
This is what reddit and youtube look like on Brave.

Please fix this. It negates a large part of the reason to block ads in the first place :(

This is underway currently in Brave Core by @Snuupy! Since this won't be addressed in our current codebase (Muon), I'm going to close this issue as wontfix
