SNOW-835641: Separate NuGet Package to Reduce Unnecessary Dependencies

[agilenut]

This library currently brings in a lot of unwanted dependencies. I'd like to propose a multi-package structure that creates a better separation of concerns and improves dependency management.

This doesn't have to be exact but I'm imagining something like this:

• Snowflake.Data.Core - Responsible for authenticating to Snowflake and providing a type-safe wrapper around the API. Should ideally have no dependencies other than the .net framework.
• Snowflake.Data.Ado - References Snowflake.Data.Core and adds the ADO.Net implementations
• Snowflake.Data.Aws - References Snowflake.Data.Core and AWS libs and adds AWS specific implementations. There would be similar packages for Azure and Google.

Then you could create a light-weight dapper style mapper like Snowflake.Client for those of us that would prefer a lighter weight interface to map to POCOs and don't need ADO.

• Snowflake.Data.Querying - References Snowflake.Data.Core and adds dapper style POCO mapping extensions.
