media: Rename CdmInfo |type| to |name|

Previously |type| was used to identify the type of a CDM (e.g. Widevine,
or Clear Key CDM). As of 5591646b86cd3526357b2775b850bcdb2189a5b4, we
use CdmInfo.guid to uniquely identify the type of a CDM to be able to
run different CDMs in different processes. Also, GUID is a much better
ID than the |type|, which is a free format text string.

With that, we don't need the |type| anymore. However, we still need a
display name for the CDM type for various purposes. For example, in the
future, we could use this name as the CDM process name.

This CL renames |type| to |name| and updated the comment.
