... such as Cuttlefish (Cloud Android virtual device) which has a DRM virtio-gpu based gralloc and (sometimes) DRM virtio-gpu based rendering (when forwarding rendering commands to the host machine with Mesa3D in the guest and virglrenderer on the host). After this change is submitted, changes such as aosp/1997572 can be submitted to removed sepolicy that is currently duplicated across device/google/cuttlefish and device/linaro/dragonboard as well. Adds a sysfs_gpu type (existing replicated sysfs_gpu definitions across several devices are removed in the attached topic). The uses of `sysfs_gpu:file` comes from Mesa using libdrm's `drmGetDevices2()` which calls into `drmParsePciDeviceInfo()` to get vendor id, device id, version etc. Bug: b/161819018 Test: launch_cvd Test: launch_cvd --gpu_mode=gfxstream Change-Id: I4f7d4b0fb90bfeef72f94396ff0c5fe44d53510c Merged-In: I4f7d4b0fb90bfeef72f94396ff0c5fe44d53510c
