[service-manager] Make instance_id a Token

Changes Identity's instance ID field from a free-form string to a
base::Token.

Prior to this change, the default instance ID was the empty string. Now
it's a zero-valued token. BindInterface attempts which do not specify an
instance ID implicitly connect to the instance with a zero-valued
instance ID.

All usage of GUIDs where relevant to instance isolation (namely media
CDM and various data decoder helpers) have been changed to Tokens.
