Translate the testing paths of pipelines and upload local test wheels

Relative paths in testing.sources and testing.environment.dependencies resolve
to their deployed workspace paths, like libraries and environment dependencies.
Local wheels in test dependencies are uploaded like other libraries, and the
same-name check covers them.

The testing property is only accepted with
DATABRICKS_BUNDLE_ENABLE_EXPERIMENTAL_PIPELINE_TESTING=true, so bundles without
it are not changed.
