Initial commit for MSI GeForce RTX 4070 12GB Gaming X Trio

I'm not sure what the process is for verifying the changes, but I followed the same pattern as in Merge Request 1634 to add my card and figured I may as well contribute.

Followed the same pattern as Commit d5bd270c
Tested on my machine (Windows 11), works with my card.
Has issues with Effects plugin (latest Pipeline release) - seems to not flush properly? (LEDs only update when effect is turned off)
