Mingyu Chen ebf45bff20 [fix](variables) change column type of @@autocommit to BIGINT (#33282)
Some of mysql connector (eg, dotnet MySQL.Data) rely on variable's column type to make connection.
eg, `select @@autocommit` should with column type `BIGINT`, not `BIT`, otherwise it will throw error like:

```
System.FormatException: The input string 'True' was not in a correct format.
   at System.Number.ThrowFormatException[TChar](ReadOnlySpan`1 value)
   at System.Convert.ToInt32(String value)
   at MySql.Data.MySqlClient.Driver.LoadCharacterSetsAsync(MySqlConnection connection, Boolean execAsync, CancellationToken cancellationToken)
   at MySql.Data.MySqlClient.Driver.ConfigureAsync(MySqlConnection connection, Boolean execAsync, CancellationToken cancellationToken)
   at MySql.Data.MySqlClient.MySqlConnection.OpenAsync(Boolean execAsync, CancellationToken cancellationToken)
   at MySql.Data.MySqlClient.MySqlConnection.Open()
```

In this PR, I add a new field of `VarAttr`: `convertBoolToLongMethod`, if set, it will convert boolean to long.
And set it for `autocommit`
