fix(debugger): type input for the program in the debug console (#1614)

A program started through runInTerminal had stdin from /dev/null, and CodeLLDB's launcher only hands the program a terminal it can read from when it runs on one. runInTerminal now starts the command on a pseudo-terminal, forwards its output to the console (CRLF as LF, without CodeLLDB's clear-screen request) and reports that the program takes input; while it runs, the console's input line goes to it, while paused it evaluates as before. debugpy and js-debug programs started in a terminal get the same.
