Enable built-in URL anti-tracking query parameters stripping

First, Arthur has added MB to https://privacytests.org/ 👍 thanks @arthuredelstein 🏅 - looks great except for the font caching which may or may not be a false positive (it happens sometimes) - need to investigate - separate issue I will follow up on @pierov FYI my bad, need coffee, it's fetch cache I really need some coffee, sorry for the noise

The other major difference I see here (say vs Brave/Librewolf) is the Tracking query parameter tests - even though it is enumerating badness, blocking the top 20 or so known offenders gives great bang for buck, and doesn't cause site issues. Initially the list was crafted by Brave and François Marier, so kudos to them. Mozilla are also starting to add this to PB mode (with a very limited list)

@fabrizio can explain how and what release Librewolf added it - there's a pref(s) [1][2] - but certainly something that can be added in the next ESR. I'm not sure what else may have been needed to make it work in normal mode, if anything.

There is also an option to use Legitimate URL Shortener in uBO, but that may cause some breakage by default - see [3] and expand the image for uBO instructions - list is maintained at [4]
