[Fix][Jdbc Connector]: Fix JdbcCatalogOptions BASE builder will be changed by call required()

[Jetiaime]

Purpose of this pull request

JdbcCatalogOptions BASE builder will be changed by call required() because it just a static variable and Builder inner list will be changed if you are using code like this:

OceanBaseCatalogFactory factory = new OceanBaseCatalogFactory();
factory.optionRule();
factory.optionRule();

So change the BASE variable to a function, when we call the base() function, it will create a new Builder, so it will be new every call;

Does this PR introduce any user-facing change?

No.
