[mle] reject `ChildIdResponse` if included dataset TLV is ill-formed (#7599)

This commit contains the following changes:

- The `Dataset` method which reads the dataset TLVs from a message
  is renamed to `ReadFromMessage()` and after reading the TLVs, it
  also checks that the TLVs in the Dataset are valid (well-formed).
- The `Active/PendingDataset::Save()` methods are updated to return
  error in the case the parsed dataset is not well-formed.
- The `Mle::HandleChildIdRequest()` rejects the response if the
  included dataset is not well-formed. This ensures that device
  stays detached if it cannot accept and save the dataset it gets
  from the parent candidate.
