fix: make using java's ServiceLoader optional

[makeevrserg]

Description

Summary of the change: Make using ServiceLoader for DatabaseConnectionAutoRegistrationnot optional

Detailed description:

• What: connectionInstanceImpl doesn't need to be created using java ServiceLoader.
• Why: In some cases with different loaders it may throw exception even if existing interface implementation is present. Also this may improve stability as reflection will not be required during connection.
• How: The connectionInstanceImpl is now lazy-loaded so even if ServiceLoader doesn't have required service, code block will not crash. Every connect method have now connectionAutoRegistration as a parameter instead of previous private-service-loaded
• This also relevant to older issues on github, which is marked as closed, but still could be reproduced located below
• This also may be a small step in migration to KMP if it's planned.
