[dataset] add API otDatasetIsValid support (#12757)

Browse Source 
This commit adds an API otDatasetIsValid to check whether the given
Operational Dataset contains all the required TLVs (Active Timestamp,
Channel, Channel Mask, Extended PAN ID, Mesh-Local Prefix, Network
Key, Network Name, PAN ID, PSKc, and Security Policy). This API also
checks whether there are duplicated TLVs or the TLVs are not
well-formed.
