[remoting] Support WirePlumber >= 0.5

The config template used by the Linux remoting host does not work with
newer versions of WirePlumber. Instead, this CL causes the host to run
WirePlumber with the default system config, but with a customized
profile.

The Debian package installs a new WirePlumber config "fragment" which
adds a custom "chrome-remote-desktop" profile. This will only be loaded
by newer WirePlumber versions which support config fragments.

Also, the environment variable $PIPEWIRE_REMOTE is added to the
session-manager child process, so that the virtual Audio/Sink device
is used by the session-manager and audio clients.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure.

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
