[CLEANUP] Add separate OutputFormat properties for arrays

`SpaceBeforeListArgumentSeparators` and `SpaceAfterListArgumentSeparators`
are added to allow for different spacing for different separators.

`SpaceBeforeListArgumentSeparator` and `SpaceAfterListArgumentSeparator`
will specify the default spacing.  Setting these as an array is deprecated.

This is the backport of #880.
