proton: Allow forwarding commands into the Proton environment

Browse Source 
Recent versions of the Steam Runtime include an IPC server/client pair
which can be used to run commands inside the container environment
(or any other special execution environment), analogous to sshd/ssh or
flatpak-portal/flatpak-spawn. The server runs inside the Steam Runtime
container and accepts commands over D-Bus; the client runs on the host
system, asks the server to run a command, and forwards its stdin, stdout
and stderr back to the host.

https://gitlab.steamos.cloud/steamrt/steamlinuxruntime/-/merge_requests/72
adds support for injecting commands into the SteamLinuxRuntime_soldier
compatibility tool (and any later version, such as sniper). However,
Steam compatibility tools are stackable: in particular, Proton runs in a
soldier container (or presumably sniper in future). If we are debugging
a Proton game, then ideally we will want to inject commands into Proton's
execution environment rather than soldier's, so that they run with the
correct environment variables etc. to communicate with a running Proton
session. In particular, it's important that the `WINEPREFIX` is correct.

The steam-runtime-launcher-interface-0 program implements the
interface for compatibility tools to use to decide where, if anywhere,
to launch the command server.

This commit does not alter the scripts produced by
PROTON_DUMP_DEBUG_COMMANDS. To run those scripts' commands in the
container environment, pass their filenames to
steam-runtime-launch-client.
