Subject: [SPARK-19012][SQL] Fix `createTempViewCommand` to throw
 AnalysisException instead of ParseException

## What changes were proposed in this pull request?

Currently, `createTempView`, `createOrReplaceTempView`, and `createGlobalTempView` show `ParseExceptions` on invalid table names. We had better show better error message. Also, this PR also adds and updates the missing description on the API docs correctly.

**BEFORE**
```
scala> spark.range(10).createOrReplaceTempView("11111")
org.apache.spark.sql.catalyst.parser.ParseException:
mismatched input '11111' expecting {'SELECT', 'FROM', 'ADD', ...}(line 1, pos 0)

== SQL ==
11111
...
```

**AFTER**
```
scala> spark.range(10).createOrReplaceTempView("11111")
org.apache.spark.sql.AnalysisException: Invalid view name: 11111;
...
```

## How was this patch tested?

Pass the Jenkins with updated a test case.

Closes #16427 from dongjoon-hyun/SPARK-19012.
