try/except xmltodict import, misc cleanups (#16287)

The 'import xmltodict' was causing import
errors when generating documentation. Since
xmltodict is a required but not stdlib module,
throw AnsibleError if unable to import.

Remove unused combine_vars.

Replace a use of 'stdin_iterator == None' with
idiomatic 'stdin_iterat is None'

Misc pep8 cleanups.
