Give developers control over TDP

[KingVulpes]

Basically, we're facing a problem where our game is allocating more wattage to the CPU than the GPU, and we don't want that, we can get away with less CPU wattage, we really need that GPU to get as much as it can and the System is not prioritizing it. So my request is you give us an option to limit the TDP for the CPU or GPU under the advanced options in Steamworks where "Override display resolution for Steam Deck external display" resides.

Currently it's due to APU internal QoS mech, very hard to change it on OS level. You can manually disable that by echo 0 | sudo tee /sys/devices/system/cpu/cpufreq/boost for now.
