IMPALA-9053: DDLs should generate lineage graphs.

DDLs like 'create table' should generate minimal lineage graphs so
that consumers like Atlas can use information like 'queryText' to
establish lineages.

This change adds a call to the computeLineageGraph() method during
analysis phase of createTable which populates the graph with basic
information like queryText. If it is a CTAS, this graph is enhanced
in the "insert" phase with dependencies.

Testing:
Add an EE test to verify lineage information and also to check it
is flushed to disk properly.
