[SPARK-14346][SQL] Native SHOW CREATE TABLE for Hive tables/views
## What changes were proposed in this pull request?
This is a follow-up of #12781. It adds native `SHOW CREATE TABLE` support
for Hive tables and views. A new field `fullyMapped` is added to `CatalogTable`
to indicate whether all table metadata retrieved from the concrete underlying
external catalog (i.e. Hive metastore in this case) can be mapped to fields in
`CatalogTable`. This flag is useful when the target Hive table contains
structures that can't be handled by Spark SQL, e.g., skewed columns and storage
handler, etc..
## How was this patch tested?
New test cases are added in `ShowCreateTableSuite` to do round-trip tests.
