Remove tight coupling of Kiota Interop code and the VS Code Extension

[thewahome]

Overview

The Kiota Interop code currently existing inside the VS Code extension can be moved to a module for reuse by the extension.
The work should separate VS Code extension specific code from the module to make it easy to extract to its own npm package

Acceptance Criteria

• The new module does not have any references to VS Code
• Unit tests for the new module implemented
