Removing tracking params from links

[chrmod]

Based on user request, we want to investigate functionality of clearurls extension.
Perhaps, there is a potential to create an open source library for other extensions to use.

Looks like the most promising path is to support removeparam in the adblocker library. This primitive would enable us to do URL cleaning through the adblocker engine.

In Manifest V3 (without blocking webRequestAPI), injecting a content script that rewrites URLs could be a way to implement it. On platforms like Firefox, which have blocking webRequestAPI, changing the URL with that API would have benefits.
