[clang-tidy] RenamerClangTidy now renames dependent member expr when the member can be resolved

Summary:
Sometimes in templated code Member references are reported as `DependentScopeMemberExpr` because that's what the standard dictates, however in many trivial cases it is easy to resolve the reference to its actual Member.
Take this code:
```
template<typename T>
class A{
  int value;
  A& operator=(const A& Other){
    value = Other.value;
    this->value = Other.value;
    return *this;
  }
};
```
When ran with `clang-tidy file.cpp -checks=readability-identifier-naming --config="{CheckOptions: [{key: readability-identifier-naming.MemberPrefix, value: m_}]}" -fix`
Current behaviour:
```
template<typename T>
class A{
  int m_value;
  A& operator=(const A& Other){
    m_value = Other.value;
    this->value = Other.value;
    return *this;
  }
};
```
As `this->value` and `Other.value` are Dependent they are ignored when creating the fix-its, however this can easily be resolved.
Proposed behaviour:
```
template<typename T>
class A{
  int m_value;
  A& operator=(const A& Other){
    m_value = Other.m_value;
    this->m_value = Other.m_value;
    return *this;
  }
};
```
