initial idea on a dbtool

[christianparpart]

This pull request introduces several enhancements and refactors to the SQL schema handling, debugging configuration, and type definitions in the codebase. The key changes include adding a new debugging configuration for vimspector, refactoring schema-related functions to use SqlConnection for better encapsulation, introducing a utility function for mapping ODBC data types, and improving type safety in migration plans.

Debugging Enhancements:

• .vimspector.json: Added a new debugging configuration for dbtool to enable launching and debugging the dbtool program with predefined arguments and settings.

Schema Handling Refactors:

• src/Lightweight/SqlSchema.cpp: Refactored schema-related functions (ReadAllTables, AllTables, etc.) to use SqlConnection instead of raw database and schema strings for improved encapsulation and clarity. Added logging for SQL execution and ensured cursors are closed after use. [1] [2] [3]
• src/Lightweight/SqlSchema.hpp: Updated function signatures to reflect the use of SqlConnection in schema-related functions. [1] [2]

Type Mapping Improvements:

• src/Lightweight/SqlColumnTypeDefinitions.hpp: Introduced the MakeColumnTypeFromNative function to map ODBC data types to SqlColumnTypeDefinition in a concise and reusable way. This replaces the previous implementation that was scattered across multiple files.
• src/Lightweight/SqlSchema.cpp: Replaced the old FromNativeDataType implementation with the new MakeColumnTypeFromNative utility for better maintainability and consistency.

Migration Plan Improvements:

• src/Lightweight/SqlQuery/MigrationPlan.hpp: Changed the tableName field in SqlCreateTablePlan from std::string_view to std::string to ensure better memory safety and ownership.
• src/Lightweight/SqlQuery/Migrate.cpp: Updated the CreateTable method to reflect the change in tableName type.

Logging and Error Handling:

• src/Lightweight/SqlConnection.cpp: Added a call to RequireSuccess for better error handling when establishing a connection.
• src/Lightweight/SqlSchema.cpp: Added detailed logging for SQL commands and error handling for unsupported data types using the new utility function. [1] [2]

These changes improve the maintainability, debugging capabilities, and robustness of the codebase, particularly in handling SQL schema operations and type mappings.
