It's not possible to implement backdrop-filter with gecko adding
explicit boundaries for backdrop roots, since backdrop filters
can sample from a backdrop in a parent iframe. In this case, the
parent display list (in one process) doesn't see a backdrop filter,
so no root display item is added, even if there is a child display
list (in another process) that has a backdrop-filter.
This patch just removes the existing backdrop-filter root display
items from Gecko. A follow up patch will add implicit backdrop
root handling inside WR itself, where we have access to all of the
display lists.
