[SPARK-14933][SQL] Failed to create view out of a parquet or orc table
## What changes were proposed in this pull request?
#### Symptom
If a table is created as parquet or ORC table with hive syntaxt DDL, such as
```SQL
create table t1 (c1 int, c2 string) stored as parquet
```
The following command will fail
```SQL
create view v1 as select * from t1
```
#### Root Cause
Currently, `HiveMetaStoreCatalog` converts Paruqet/Orc tables to `LogicalRelation` without giving any `tableIdentifier`. `SQLBuilder` expects the `LogicalRelation` to have an associated `tableIdentifier`. However, the `LogicalRelation` created earlier does not have such a `tableIdentifier`. Thus, `SQLBuilder.toSQL` can not recognize this logical plan and issue an exception.
This PR is to assign a `TableIdentifier` to the `LogicalRelation` when resolving parquet or orc tables in `HiveMetaStoreCatalog`.
## How was this patch tested?
testcases created and dev/run-tests is run.
