Rename nsIJumpListBuilder to nsILegacyJumpListBuilder
Add createLegacyJumpListBuilder to nsIWinTaskBar to use the old mechanism
Update WindowsJumpList to use the legacy interface
Create a new nsIJumpListBuilder
Document NativeJumpListBackend
Populate nsIJumpListBuilder using the code we developed in the previous iteration
Have createJumpListBuilder in nsIWinTaskBar use that

It’s working! It’s just that you have to remember to actually remove the item for it to show up in the list.
Update WindowsJumpLists to choose the right builder based on the pref and treat them correctly based on that pref.
Write a gtest for the JumpListBuilder
Write a front-end test that registers a fake nsIWinTaskbar or otherwise produces a fake nsIJumpListBuilder to make sure it gets passed the right things.
Make a note to migrate the new jump list builder off of the dedicated lazy thread and use the IO thread pool instead.
