Currently, we use the script principal to verify the client to prevent
the principal forgery. After we moving to use foreign partitioned
principal for the Client, this no longer works. Instead, we can directly
use the client's principal to verify client.
Also, the patch rename StoragePrincipalHelper::VerifyValidStoragePrincipalInfoForPrincipalInfo() to
StoragePrincipalHelper::VerifyValidPartitionedPrincipalInfoForPrincipalInfo()
and fix a problem in the function that it should ignore the PartitionKey
instead of the FirstPartyDomain.
