Provide BCC in WVDrmFactory dumpsys.

Browse Source 
[ Merge of go/wvgerrit/c/cdm/+/165138 ]

Enabled the Widevine DRM service on Android to return the raw boot
certificate chain via the CDM status query capabilities.  This
property key is not available for app-level queries.

The BCC is dumped by the WVDrmFactory when requested to print all
CDM properties via dumpsys.

Bug: 234095402
Test: request_license_test
Test: adb shell dumpsys android.hardware.drm.IDrmFactory/widevine -p
