IMPALA-14408: Use regular path for Calcite planner instead of CalciteJniFrontend

Browse Source 
When the --use_calcite_planner=true option is set at the server level,
the queries will no longer go through CalciteJniFrontend. Instead, they
will go through the regular JniFrontend, which is the path that is used
when the query option for "use_calcite_planner" is set.

The CalciteJniFrontend will be removed in a later commit.

This commit also enables fallback to the original planner when an unsupported
feature exception is thrown. This needed to be added to allow the tests to run
properly. During initial database load, there are queries that access complex
columns which throws the unsupported exception.
