BCD and spec, tidy up for consistency

[rachelandrew]

Adds the spec and BCD to these pages. See BCD PR mdn/browser-compat-data#11631

Reviewer: @jpmedley

Joe, these came up as missing in the spreadsheet. They did exist but didn't have BCD (only the main interface did). While sorting that out I have also updated these pages for consistency as the main page was one with IDL info on it.
