fix: Include SDK source files when executing examples

- Pass SDK files via input_files parameter to /tmp/
- Prepend import path fix for Python and Ruby
- Also made some examples standalone as fallback

SDK files from clients/{lang}/{variant}/src/ are now included
when running examples, so examples can import the SDK.
