Clean up VariableDeclaration and MemberDeclaration APIs.

- Adds hasInitializer and hasConst to VariableDeclaration.
- Renames isStatic to hasStatic to be consistent with other members.
- Improves serialization tests by randomizing some values, which
  should help to catch ordering errors in serialization.
