Synchronise renderdoc.conf on all remote device platforms

[cmannett85-arm]

Aligns remote Linux with Android behaviour, by pushing the host's renderdoc.conf to the remote device. Preivously that was done only on Android via ADB, whereas now it is done over the server connection itself.

The slight regression here is that previously on Android the conf file was pushed before server start so the initial connection used the RemoteServer_TimeoutMS setting, whereas now that will be set upon first reconnection. All other settings are unaffected.

I understand the reasoning for this change, but I don't think it's generally applicable and I think you should keep it locally.

We manage the config explicitly for Android primarily because we can know as a platform that it's by definition always remotely managed (you don't run the UI locally) and only ever has one client by its nature. As as side benefit because Android is such a terrible, awful, disaster of a platform even having to copy a file is painful so handling this ourselves is useful.

That primary reason doesn't hold for remote replay in general because you may be remote replaying on a machine that already has its own config and we can't unilaterally overwrite it. Also anywhere else but Android it's much easier to copy a file across or even run the UI to manage it locally on the remote.
