Query analog output capabilities.

[ Merge of http://go/wvgerrit/107763 ]

This CL enables the ability to query the CDM for the analog output
capabilites of the device.  Due to the number of possibilities that
OEMCrypto can report, two queries are exposed:
- Output capabilities: None, Supported, CGMS-C, Unknown
- Can disable: True, False, Unknown
