    Bug 1718878 - Updates to the build system to enable compatibility with Python 3.10 (Mainly regarding collections.abc) r=mhentges,webdriver-reviewers,whimboo a=RyanVM
    
    Previously, collections.abc was available from the collections import. In Python
    3.10, they were explicitly moved to collections.abc. As such, any references to
    collections abstract base classes need to import collections.abc in Python 3.10.
