Bug 1814686 - Part 1a: Wrap refcounted types in NotNull by default, r=ipc-reviewers,mccr8

Browse Source 
These are the IPDL compiler changes to make all refcounted types be considered
NotNull by default, building on the changes from bug 1607634.

Existing uses of IPDL refcounted types will be marked as nullable in part 1b.
