Copy Clean URL on links in page

[bsclifton]

Description

Follow up to #23315

For employees wanting to see the spec (by @fmarier), go on GDrive and search for Copy clean URL

For the MVP of the original feature, it only shows in two places.

1. Share widget
   
2. Right clicking omnibox (url bar)
   

This functionality should also be on in-page links (when you right click). For example, here:

From the spec:

We could have a Copy clean link address option there too, but it requires more work since in that case we’ll have to first apply our normal URL modification rules (e.g. debouncing, query filter, de-AMP, HTTPS Everywhere) before applying the clean URL filter.

In order to ship the feature faster, this context menu will not be part of the MVP and will be addressed in a follow-up later.

Just a FYI had an issue with this feature in Brave Beta as outline in my post on Brave subreddit

Closing, not sure when we added it to content menu though.
