nit: I think whether it's "Supported" is more a property of a value returned by
GetSupportedProfiles than it is the type (Though I'm not sure if we'd use the
type for anything else).

Nonetheless...  a name like PP_VidepProfileDescription might be better?

Acknowledged.

This tries to follow the VEA api, where the class is VEA::SupportedProfile.
https://code.google.com/p/chromium/codesearch#chromium/src/media/video/video_...

This type may in future be used by VideoDecoder, as there's an outstanding bug
to add similar querying there.

PP_VideoProfileDescription is a good name too. Done.
