clang-format: Lower binding strengths created by the [] created by ObjC

method expressions and array literals. They should not bind stronger
than regular parentheses or the braces of braced lists.

Specific test case in JavaScript:
Before:
  var aaaaa: List<
      SomeThing> = [new SomeThingAAAAAAAAAAAA(), new SomeThingBBBBBBBBB()];

After:
  var aaaaa: List<SomeThing> = [
    new SomeThingAAAAAAAAAAAA(),
    new SomeThingBBBBBBBBB()
  ];
