Add support for wrapping system streams in WorkRequestHandler

There are often [places](https://github.com/bazelbuild/bazel/blob/ea19c17075478092eb77580e6d3825d480126d3a/src/tools/android/java/com/google/devtools/build/android/ResourceProcessorBusyBox.java#L188) where persistent workers need to swap out the standard system streams to avoid tools poisoning the worker communication streams by writing logs/exceptions to it.

This pull request extracts that pattern into an optional WorkerIO wrapper can be used to swap in and out the standard streams without the added boilerplate.

Closes #14201.
