Build more robust sql batch parser

[rdagumampan]

An sql batch statements is a group of sql statements executed in a single call. In SqlServer, a batch scripts are group of statements in a single .sql file terminated by "GO". In Snowflake and other platforms, the terminator is a semicolon ";".

The current strategy is not robust enough to handle this and delegated the breakdown of statements to the platform implementation. It would be better to take this capability in Yuniql.Core, have some default BatchTerminator in the implementation of IDataService. The BatchTerminator can also be parameterized such as --batch-terminator GO or --batch-terminator ;
