Internal BCC extraction tool to consume verified device info

Browse Source 
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
