Remove links to -moz features not available to the web

[teoli2003]

This PR removes mentions and links to Mozilla CSS extensions unavailable to websites. They will never be documented, and hid the actual experimental extensions available to web developers.

• -moz-binding. No more available on the web platform since Firefox 67.
• -moz-border-*-colors. No more available on the web platform since Firefox 60.
• -moz-outline-radius-* Removed more than 2 years ago (Firefox 88) -> delete
• -moz-window-dragging. Chrome-only.
• -moz-window-shadow. Not available on the web platform since Firefox 44.
• -moz-tree-* XUL only, long gone.

Additional information

• Remaining flaws are links to pages that should be documented or entries I have yet to find information about. There are still plenty of them, but the Mozilla extension page was one of the pages with the largest amount of flaws on MDN (3% of the total on one page!). This PR removes 1/3 of the flaws on that page
• I have not fixed other flaws on Firefox XY for developers—only the ones related to this cleaning.
• There are fewer properties nowadays; grouping them is no longer needed. (Still needed for pseudo-classes and elements)
