  clang-format: fix spacing in `operator const char*()`

Summary:
Revision a75f8d98d7ac9e557b238a229a9a2647c71feed1 fixed spacing for operators,
but caused the const and non-const versions to diverge:
```
// With Style.PointerAlignment = FormatStyle::PAS_Left:

struct A {
  operator char*() { return ""; }
  operator const char *() const { return ""; }
};

```
The code was checking if the type specifier was directly preceded by `operator`.
However there could be comments and `const/volatile` in between.
