[SPARK-12728][SQL] Integrates SQL generation with native view
This PR is a follow-up of PR #10541. It integrates the newly introduced SQL
generation feature with native view to make native view canonical.
In this PR, a new SQL option `spark.sql.nativeView.canonical` is added.
When this option and `spark.sql.nativeView` are both `true`, Spark SQL tries to
handle `CREATE VIEW` DDL statements using SQL query strings generated from view
definition logical plans. If we failed to map the plan to SQL, we fallback to
the original native view approach (i.e., wrap the original view definition SQL
text with an extra `SELECT` clause.
