feat: add CODER_CLUSTER_HOST CLI argument (#26680)

Closes GRU-69

Adds CODER_CLUSTER_HOST enviroment variable and CLI arg.

I ended up not making it hidden since we'll just have to unhide it later and even when hidden it still shows up in some autogenerated stuff. Might as well just go for it.

I also added it to the helm chart.
