Internal factory tool implements CSR v3

Browse Source 
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
