feat: rewrite libdrm ioctl bridge with VirtGPU support

Browse Source 
Wire P1/P2 patches into recipe.toml. Source reflects the full ioctl bridge\nrewrite: VirtGPU NR mappings, EXECBUFFER/GET_CAPS special handlers,\nPCI info bridge for drmGetDevice2, and removal of the old per-ioctl C\nhandler functions in favor of unified redox_drm_simple_ioctl() dispatch.

Ultraworked with [Sisyphus](https://github.com/code-yeongyu/oh-my-openagent)
