clang-format: Correctly format alias declarations.

Before:
  template <class CallbackClass>
  using MyCallback = void(CallbackClass::*)(SomeObject * Data);");

After:
  template <class CallbackClass>
  using MyCallback = void (CallbackClass::*)(SomeObject *Data);");

Also fix three wrong indentations.
