Support Platform Specific vsix files

[mohitsuman]

In the release of vscode 1.61.0, VSCode will support platform-specific libraries or dependencies to be added with the vsix file. For OpenShift Connector, we need to bundle the dependencies accordingly for the platform.

Acceptance Criteria

• To publish a package for each and every platform that your extension supports.
• The currently supported platforms are: win32-x64, linux-x64, darwin-x64
