MouseEvent - remove experimental on features and tidy

[hamishwillee]

Fixes #10120

MouseEvent.offsetX and offsetY were marked as experimental. As per mdn/browser-compat-data#13206 they are not. This removes the markup.

A bunch of other cases were marked experimental too. This removes those as appropriate, also fixes up syntax sections and general layout changes for all properties. There were some cases where docs said "refer to browser compat for more information" where said information is not provided - so I removed those comments too.

Two sentences to remove, I believe. Else this is a nice clean-up! Thanks.
