platform_chrome: cros_ec: Add Type-C VDM defines

Browse Source 
Add the EC header changes need to support USB Type-C VDM (Vendor Defined
Messages) communication between the system and USB PD-enabled
peripherals.

The headers are already present in the EC code base, from which they've
been ported [1].
