LGTM, thanks for the PR.

Should we add a small test like the one below to check behaviour when both implicit and explicit mapping is used in the same construct?
I'm expecting `obj` still uses the implicit default mapper, and we also emit an explicit map entry for `obj%ptr_scalar` (i.e. explicit component mapping is not suppressed by the new implicit-pointer skip).

```
!$omp target map(mapper(default), tofrom: obj) map(tofrom: obj%ptr_scalar)
    obj%id = obj%id + 1
!$omp end target
```
