RemoteExecutionService: Action.Command to set output_paths (#18440)

This is a follow-up to #18198

Make Bazel compatible with newer version of Remote Api by setting
output_paths along-side output_directories and output_files. The latter
2 are deprecated in newer REAPI specification.

Closes #18202.
