fix: propagate execArgv (#5510)
* Use fork instead of spawn

We no longer do in-place updating so no need for the spawn.  The
advantage of a fork is that it preserves flags like --prof which you can
use to profile code-server.

Also I am not sure the comment about not being able to reload in place
with fork was even true to begin with.

* Refresh heartbeat patch

Seems to have gotten out of date a little.

* Propagate execArgv to extension host

This will let us profile the extension host.

Add a heartbeat to web socket connections
This prevents them from being killed when they are idle. To test run behind
NGINX, make sure the sockets are idle (check dev tools), then wait 60+ seconds.
