feat(vscode): add option to control extension activation per scope

Add new `robotcode.disableExtension` configuration setting that allows
users to disable or enable the RobotCode extension at any scope level.

With resource scope, users can:
- Disable the extension globally (user settings) and enable it for
  specific workspaces or folders
- Disable the extension for a workspace and enable it for specific
  folders within
- Disable the extension only for specific folders in multi-root
  workspaces

This is useful in:
- Large workspaces where RobotCode is not needed everywhere
- Multi-root workspaces with mixed project types
- Environments where users want opt-in rather than opt-out behavior

Changes:
- Add `disableExtension` boolean setting with resource scope
- Skip language client creation when extension is disabled
- Disable test explorer for disabled workspace folders
- Add "Disable" option to Python environment selection dialog
- React to `disableExtension` configuration changes for restart

closes #527
