MdeModulePkg/NvmExpressPei: Add logic to produce SSC PPI
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1409
For the NvmExpressPei driver, this commit will add codes to produce the
Storage Security Command PPI if the underlying NVM Express controller
supports the Security Send and Security Receive commands.

+ Send a security protocol command to a device that receives data and/or the result
+ of one or more commands sent by SendData.
+
+ The ReceiveData function sends a security protocol command to the given DeviceIndex.
+ The security protocol command sent is defined by SecurityProtocolId and contains
+ the security protocol specific data SecurityProtocolSpecificData. The function
+ returns the data from the security protocol command in PayloadBuffer.
+
+ For devices supporting the SCSI command set, the security protocol command is sent
+ using the SECURITY PROTOCOL IN command defined in SPC-4.
+
+ For devices supporting the ATA command set, the security protocol command is sent
+ using one of the TRUSTED RECEIVE commands defined in ATA8-ACS if PayloadBufferSize
+ is non-zero.
+
+ If the PayloadBufferSize is zero, the security protocol command is sent using the
+ Trusted Non-Data command defined in ATA8-ACS.
+
+ If PayloadBufferSize is too small to store the available data from the security
+ protocol command, the function shall copy PayloadBufferSize bytes into the
+ PayloadBuffer and return EFI_WARN_BUFFER_TOO_SMALL.
+
+ If PayloadBuffer or PayloadTransferSize is NULL and PayloadBufferSize is non-zero,
+ the function shall return EFI_INVALID_PARAMETER.
+
+ If the given DeviceIndex does not support security protocol commands, the function
+ shall return EFI_UNSUPPORTED.
+
+ If the security protocol fails to complete within the Timeout period, the function
+ shall return EFI_TIMEOUT.
+
+ If the security protocol command completes without an error, the function shall
+ return EFI_SUCCESS. If the security protocol command completes with an error, the
+ function shall return EFI_DEVICE_ERROR.
+
+ @param[in] This The PPI instance pointer.
+ @param[in] DeviceIndex Specifies the storage security device to which the
+ function wants to talk. Because the driver that
+ implements Storage Security Command PPIs will manage
+ multiple storage devices, the PPIs that want to talk
+ to a single device must specify the device index
+ that was assigned during the enumeration process.
+ This index is a number from one to NumberofDevices.
+ @param[in] Timeout The timeout, in 100ns units, to use for the execution
+ of the security protocol command. A Timeout value
+ of 0 means that this function will wait indefinitely
+ for the security protocol command to execute. If
+ Timeout is greater than zero, then this function
+ will return EFI_TIMEOUT if the time required to
+ execute the receive data command is greater than
+ Timeout.
+ @param[in] SecurityProtocolId
+ The value of the "Security Protocol" parameter of
+ the security protocol command to be sent.
+ @param[in] SecurityProtocolSpecificData
+ The value of the "Security Protocol Specific"
+ parameter of the security protocol command to be
+ sent.
+ @param[in] PayloadBufferSize
+ Size in bytes of the payload data buffer.
+ @param[out] PayloadBuffer A pointer to a destination buffer to store the
+ security protocol command specific payload data
+ for the security protocol command. The caller is

+ A pointer to a buffer to store the size in bytes
+ of the data written to the payload data buffer.
+
+ @retval EFI_SUCCESS The security protocol command completed
