5e24549b1a Internal factory tool implements CSR v3
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

a880498f36 Internal BCC extraction tool to consume verified device info
BCC extraction tool calls OEMCrypto_GetDeviceInformation() to read
verified device info from TEE. If the verified device info is not
available, (e.g. not implemented), it falls back to using OS properties.

This CL changes the tool used by widevine internally. Another CL will
update the tool for factory use.

Test: Ran the tool on Pixel 7 w/wo verified device info being present
