[clang-tidy] Add `IgnoreAliasing` option to `readability-qualified-auto check` (#147060)

`readability-qualified-auto` check currently looks at the unsugared
type, skipping any typedefs, to determine if the variable is a
pointer-type. This may not be the desired behaviour, in particular when
the type depends on compilation flags.
For example

```
 #if CONDITION
      using Handler = int *;
  #else
      using Handler = uint64_t;
  #endif
```

A more common example is some implementations of `std::array` use
pointers as iterators.

This introduces the IgnoreAliasing option so that
`readability-qualified-auto` does not look beyond typedefs.
