Added a new global rule for Evidon

[Greg-21]

When reviewing, please keep in mind that this is my first/one of the first attempts to make a global rule public and available to all users. I have done my best to test everything thoroughly on various websites, but I'm afraid that due to my lack of experience in this regard, I may have messed something up, and the rule will not work as expected (in some corner cases, for example).

In this pull request, I propose adding support for the Evidon CMP, which is used in the wild by various websites on the Internet, and removing the site-specific rules that will no longer be necessary thanks to this new global rule.

Resolves #350

Hi! Thanks for looking into more global / CMP rules! For visibility: #301 (comment)

After sleeping on it, I've come to the conclusion that it's probably best to hold off on this pull request for now, as I'm afraid that there may be more websites like crunchyroll.com that use the #_evidon-decline-button ID with a cookie accept button, which in their opinion probably means something like "Do whatever you want, I don't care about cookies". I just hope there aren't many websites like theirs in the wild...

Trikolon, thank you for making sure I'm aware of the potential complications, but since I've been using these global rules privately for a few weeks now, I have finally decided to publish them while I still have some free time. It's now or never :)
