clang-format: [JS] Assign proper penalties when breaking a type annotation

Before:
  class Test {
    aaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaa:
                         aaaaaaaaaaaaaaaaaaaaaaaa): aaaaaaaaaaaaaaaaaaaaaa {}
  }

After:
  class Test {
    aaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaa: aaaaaaaaaaaaaaaaaaaaaaaa):
        aaaaaaaaaaaaaaaaaaaaaa {}
  }
