CreateDmlService()
Override to opt-in to provider-specific DML mechanics (currently: "is this exception a
table-not-found" detection used by DropTable(throwExceptionIfNotExists: false)).
Providers whose DROP TABLE already expresses "if exists" in SQL don't need this —
leave it returning null and no suppression will be attempted.

GetQueryParameterNormalizer()
Returns instance of <xref href="linq2db%3a%3aLinqToDB.Internal.DataProvider.IQueryParametersNormalizer" data-throw-if-not-resolved="false"></xref>, which implements normalization logic for parameters of single query.
E.g. it could include:
<ul><li>trimming names that are too long</li><li>removing/replacing unsupported characters</li><li>name deduplication for parameters with same name</li></ul>
. For implementation without state it is recommended to return static instance. E.g. this could be done for providers with positional parameters that ignore names.
