BES: Consolidate BuildEventServiceModule and BuildEventStreamerModule.

After having open sourced the Build Event Service code, there is no more need
to have two separate bazel modules that both create a BuildEventStreamer.

This change merges the BuildEventStreamerModule logic into the
BuildEventServiceModule.
