Add controller motion support

[FallingSnow]

I wanted to add support for client side cursors (https://github.com/LizardByte/Sunshine/discussions/1276) but figured that might be a little complicated. So I decided to start with another issue I was having, controller motion. I play Zelda: BOW on CEMU via moonlight. There are areas that require controller motion input which I can test on.

I know that this will probably require some tweaks to sunshine too. I had a couple of questions/comments:

• SDL_GameControllerGetSensorDataRate reports 1000hz for the PS5 controllers gyro. 1000pps might be a lot so can I reduce this to say 2x target frame rate or maybe just 60pps?
• It does appear that ViGEmBus supports motion: Add touchscreen support for the Dualshock 4 touchpad nefarius/ViGEmBus#11
• What kind of sunshine changes would need to be made?
• Would I just add gyro info to NV_MULTI_CONTROLLER_PACKET to send it over the network? What's the best way to do this while maintaining backwards compatibility?

Thanks, I ended up including a controller motion packet extension in my latest batch of Sunshine protocol extension in moonlight-common-c.
