feat(csgoserver): support the standalone CS:GO client (App ID 4465480) with configurable clientappid and the NoLobbyReservation mod (#4963)

* feat(csgoserver): support the standalone CS:GO client (App ID 4465480) with configurable runtimeappid and the NoLobbyReservation mod

* feat(csgoserver): rename runtimeappid to clientappid, pin NoLobbyReservation, prefer spcomp64

- Rename runtimeappid to clientappid and reword the comments: appid is
  the SteamCMD download ID (740), clientappid is the App ID the server
  advertises and players' clients connect with (4465480 or 730).
- Pin NoLobbyReservation to commit 003ab19f. It has no releases and is
  compiled from source on install, so do not follow master.
- Prefer spcomp64 and fall back to spcomp, so compiling does not rely
  on i386 libraries.
