Auto-detect GPU and select optimal graphics driver for new containers

[gigachadmma69]

Summary

• Detect the device GPU at container creation time and default to the optimal graphics driver
• Adreno GPUs: default to Turnip + DXVK (best performance path)
• Mali / PowerVR / other GPUs: default to VirGL + WineD3D (compatible path)

Problem

Currently, all new containers default to turnip regardless of the actual GPU hardware. This causes immediate black screens or crashes on non-Adreno devices (Samsung Exynos with Mali, MediaTek Dimensity with Mali, etc.). Users have to manually discover they need to switch to VirGL, which is unintuitive and the most common source of "nothing works" first-run reports.

Changes

GPUInformation.java -- Added GPU family detection methods:

• isAdreno() / isMali() / isPowerVR() -- detect GPU family from GL_RENDERER string
• getRecommendedGraphicsDriver() -- returns "turnip" for Adreno, "virgl" for others
• getRecommendedDXWrapper() -- returns "dxvk" for Adreno, "wined3d" for others

ContainerDetailFragment.java -- When creating a new container (not editing existing), use the detected GPU's recommended driver/wrapper instead of the hardcoded turnip/dxvk defaults.

Impact

• Zero behavior change for Adreno users (still defaults to turnip)
• Immediate fix for Mali/PowerVR users who currently get broken first-run experience
• Existing containers are not affected (only applies when creating new containers)

Test plan

• Create new container on Adreno device -- should default to Turnip + DXVK
• Create new container on Mali device -- should default to VirGL + WineD3D
• Edit existing container -- should show current saved values, not auto-detected
• Override auto-detected defaults manually -- should work as before

So problem when I download games

@brunodev85 🙏🏻
ability to add turnip drivers using bylaws turnip tool will be good for newer devices

Similarly, ability to automatically detect or at least manually set/override to the more performant CPU topology would be nice - both custom masks and custom order. Notably, at least in my usage with Retroid pocket G2, it seems to completely ignore environment variables I try to adjust it with, or even the GUI's own affinity settings, leaving the most powerful core seemingly completely unutilized, and the order in which it's using the cores is inverted - using the weakest cores for the main thread. I suspect it's something to do with how hardcoded container setup might be? It should be made easy to override, not whatever it's doing right now.

Op your idea is great but how you explained it is not, let me explain
Every gpu has different vulkan version and opengl es version, and every driver vulkan or gl based have different minimum requirements, so the auto-ness of this system comes to if the version of driver is compatible but as Bruno has done great work in co-implementing both only the requirements part is the issue, so if the system detects vulkan 1.1 or above it selects the compatible or at least to requirements and vice versa for gl , so it's not that you have Snapdragon or mali or something else it's driver based (if any thing I said is wrong please correct me)
