Add support for multiple test runtimes

The `runtime-paths` input can now be used to provide a YAML format list of paths to runtimes when multiple are generated.

The previous `runtime-path` input can still be used as usual. A deprecation warning will be shown in the log when this
input is used.

The default behavior is unchanged.
