Factory tool implements Widevine IRPC HAL v3

Browse Source 
Implement IRPC HAL v3 interfaces for extracting device registration CSR.
The new interface calls OEMCrypto_GetDeviceInformation() and
OEMCrypto_GetSignedCsrPayload() and then constructs the CSR.

Also added all mandatory fields of device info in the request.

Test: Run extraction tool on Pixel 7 and upload CSR
Test: Verified Widevine remote provisioning
