Experimental support for AMD Renoir

This adds the GFX version 9.0.0 in order to use Renoir GPUs with at least 4 GB of VRAM (it's possible to increase the virtual VRAM from the BIOS settings of some vendors). This will only work if the remaining ram is at least 12 GB to avoid the system to become unresponsive on launch.).
This change also changes the GPU check to a case statement to be able to add more GPUs efficiently.

This commit specifies which GPUs should use the GFX variable, RDNA 3 is excluded since it uses a newer GFX version
