This commit enhances the handling of `Timestamp`. Methods `SetToInvalid()` and `IsValid()` are added to the `Timestamp` class. The value where all bytes are set to `0xff` is used to represent an invalid `Timestamp`. This corresponds to max seconds, max ticks with the authoritative (`U`) flag set. This helps simplify `DatasetManager`, where we need to track local and network Active/Pending timestamps, which may not be present. These are now represented by setting the `Timestamp` to the invalid value (replacing the earlier model where a `Timestamp` pointer was used with `nullptr` representing an invalid timestamp). This allows us to simplify the `Timestamp::Compare()` method, now getting two `Timestamp &` instead of `Timestamp *`. With this, we can also define comparison operator overloads to compare two `Timestamp` objects, which helps make the code simpler and more readable.
