Widevine internal BCC extraction tool to extract CSR v3 for testing purpose. The difference it has from the factory tool is it doesn't rely on Widevine IRPC HAL. It just extracts BCC/CSR in the specified format from cli. Test: Extract CSR v3 on Pixel 7 and upload Bug: 268246995 Change-Id: I52abe09f991c89c6e7601bcef4d980f24c020c9f
