[SPARK-21739][SQL] Cast expression should initialize timezoneId when it is called statically to convert something into TimestampType

This issue is caused by introducing TimeZoneAwareExpression.
When the **Cast** expression converts something into TimestampType, it should be resolved with setting `timezoneId`. In general, it is resolved in LogicalPlan phase.

However, there are still some places that use Cast expression statically to convert datatypes without setting `timezoneId`. In such cases,  `NoSuchElementException: None.get` will be thrown for TimestampType.

This PR is proposed to fix the issue. We have checked the whole project and found two such usages(i.e., in`TableReader` and `HiveTableScanExec`).
