Title:
SRU: Set on-demand as default, enable RTD3 only on laptops and
decouple on-demand with RTD3

Status in nvidia-prime package in Ubuntu:

Status in nvidia-prime source package in Focal:

Status in nvidia-prime source package in Hirsute:

Bug description:
[Impact]
* Ubuntu will set GPU mode to performance as default which may use more power
* User can't use GPU for other purpose (eg: deep-learning) if RTD3 is not
supported
* According to Nvidia README, the RTD3 doesn't support on non-laptop machine
[Test Plan]
* Install Ubuntu, and then execute 'ubuntu-drivers install' to install GPU
driver. After the installation, reboot the system. Execute "prime-select query"
should get "on-demand"
* On non-laptop machine. Can set GPU mode to on-demand
* On laptop with GPU in runtime PM support list. Set GPU mode to on-demand
and Nvidia driver is loaded with "NVreg_DynamicPowerManagement=0x02"
[Where problems could occur]
* on-demand mode supported after nvidia driver 450. And focal does not have
nvidia driver lower than 450.
* With GPU supported RTD3 not able enable runtime PM on non-laptop. But
based on the Nvidia README, this case shall not happened.
