Dropped the dependency on TagInfo from LArG4GenShowerLib

This commit is a part of the effort to reduce the number of clients of TagInfo in Athena to the bare minimum. After that the TagInfo handling mechanism should be redesigned, in order to make it MT-compliant.

LArG4GenShowerLib used TagInfo only for querying it for the release information. The latter information can be obtained from the environment variables instead.
