[clang-tidy] misc-const-correctness false positive with ->* operator

[BenBudr]

Minimal example of member access via pointer-to-member via pointer-to-object causing false positive:

struct S { int i; };

void a(int &) {}

int main()
{
  S s;
  S * sp = &s;
  a(sp->*(&S::i));
}

<source>:8:3: warning: pointee of variable 'sp' of type 'S *' can be declared 'const' [misc-const-correctness]
    8 |   S * sp = &s;
      |   ^
      |      const
1 warning generated.

Applying the suggested fix-it would cause a compilation error.
