Reduce Alignment handler struct to a single function.

TabluarAlignTokens() interface is now thinner and more flexible in allowing the
callers to return AlignablePartitionGroups that can each have their own column
extraction function.

ExtractAlignmentGroupsAdapter() still works for cases where one wishes to only
handle one type of subrange aligment per syntax-tree node type.
