The412BannerandDersim Abbas 1c758abd04 Mali (Venus) as a selectable route, by David Cimo ...

Ports David Cimo's Venus route (DavidCimo/droiddeck-mali, mali-venus @ 4f838891) onto this branch
as "Mali (Venus)", one tap in Setup next to the Mali bridge:
- VenusComponent (his): stages the Venus ICD and runs virglrenderer's vtest server over the
  phone's own Vulkan driver; the guest gets VK_ICD_FILENAMES, VN_DEBUG=vtest, VTEST_SOCKET_NAME and
  MESA_VK_WSI_DEBUG=sw.
- Selection rule: Venus when Setup's "Mali (Venus)" is on, on a GPU that is neither an Adreno nor
  a system-driver one (PowerVR, Xclipse), and the apk carries it. It then replaces the Mali bridge
  and any open driver pair for the session, and the display stays on the phone's own driver.
  Auto is unchanged (the PanVK pair). Adreno never takes any of it.
- The compositor enables only the dma-buf extensions the driver has, logs a vendor driver's
  extension list, and gives a zero row pitch a packed row (his vk_present.c changes).
- The Mali compatibility layer is staged into the runtime on non-Adreno devices only.
- The component (vtest server, ICD, layer) comes from build-venus.yml as venus.tzst, published on
  The412Banner/droiddeck-nonadreno-drivers and pinned by sha in tools/venus/release.env.
- gamescope 3.16.29-p15 adds his shm upload patch (0127) next to 0126; pinned by sha.
- device.txt and graphics-report.txt name the route.
