[clang-format] Fine-grain control for AlignConsecutiveDeclarations

[EugeneZelenko]

Currently AlignConsecutiveDeclarations has AlignFunctionDeclarations to enable/disable alignment for function. It'll be good idea to add similar options for variables and data members.

My work project consistently align data members, but use mixed formatting for variables, so it's necessary to enable alignment only for data members.

Same is true for AlignConsecutiveAssignments.
