There is no PowerCLI cmdlet to install VMware Tools, since there is no API method to do that either (like there is for upgrading VMware Tools).
You also can not use Invoke-VMScript, since that requires the presence of VMware Tools.
Most new Linux distributions have VMware Tools integrated, aka GuestManaged.
On a Windows guest OS you will have to use the mechanism that you normally use to install SW, via an agent or manually.
There is an option to install the VMware Tools silently, but that command needs to be given inside the guest OS.
