Add support for SBProcess::PutSTDIN to remote processes

Processes running on a remote target can already send $O messages
to send stdout but there is no way to send stdin to a remote
inferior.

This allows processes using the API to pump stdin into a remote
inferior process.

It fixes a hang in TestProcessIO.py when running against a remote
target.
