SqlStatementCompiler Not Support JDBC Function DATABASE()

## Bug Report

**For English only**, other languages will not accept.

Before report a bug, make sure you have:

- Searched open and closed [GitHub issues](https://github.com/apache/shardingsphere/issues).
- Read documentation: [ShardingSphere Doc](https://shardingsphere.apache.org/document/current/en/overview).

Please pay attention on issues you submitted, because we maybe need more details.
If no response anymore and we cannot reproduce it on current information, we will **close it**.

Please answer these questions before submitting your issue. Thanks!

### Which version of ShardingSphere did you use?
5.4.1
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
sharding-jdbc
### Expected behavior
SqlStatementCompiler can compile DATABASE() Function
### Actual behavior
Throw Exception: No match found for function signature DATABASE()
Detail:
```
org.apache.calcite.runtime.CalciteContextException: At line 0, column 0: No match found for function signature DATABASE()

### Reason analyze (If you can)
SQLStatementCompiler try to use calcite's SqlUtil to validate sql, but it only try to match standard function and operator(not contains DATABASE() function)
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc.
Try to use org.apache.shardingsphere.sqlfederation.optimizer.it.SQLStatementCompilerIT with these code to reproduce the problem:
```
@Test
void testJDBCFunctionDataBase() {
String sql = "select DATABASE()";
SQLStatement sqlStatement = sqlParserRule.getSQLParserEngine(TypedSPILoader.getService(DatabaseType.class, "MySQL")).parse(sql, false);
SQLFederationExecutionPlan plan = sqlStatementCompiler.compile(sqlStatement, "MySQL");
}

@Test
void testJDBCFunctionDataBaseEscape() {
String sql = "select {fn DATABASE()}";
SQLStatement sqlStatement = sqlParserRule.getSQLParserEngine(TypedSPILoader.getService(DatabaseType.class, "MySQL")).parse(sql, false);
SQLFederationExecutionPlan plan = sqlStatementCompiler.compile(sqlStatement, "MySQL");
}
```
