[pipeline-connector][doris] Extract type mapping logic

[JNSimba]

Currently in DorisSink, the type mapping logic directly reuses the Flink Doris Connector. Although it is more convenient, it forms a strong binding relationship with the connector in terms of freedom, which greatly reduces the degree of freedom.
So the Doris type mapping is extracted here.

Maybe ,we can add TimeType in DorisTypeMapper to fix #3099.
