Don't send run/test code lenses for clients that don't support debugging

[olafurpg]

Describe the bug

Using any other editor than VS Code with the latest snapshot shows "run" and "test" code lenses even if the editor is unable to implement the client commands to run and test via Debug Adapter Protocol.

Expected behavior

Metals should not show code lenses for clients that don't include the debuggingProvider = true field in client capabilities, see
