Squash of Droid-Deck/DroidDeck#517 (ASEbrahim/DroidDeck mali-bridge @ 6b823341): the Vulkan
bridge (tools/vkbridge) that runs the guest's Vulkan on the phone's own driver, with BC1-BC7,
clip/cull distance, vertex-divisor and depth-clip emulation and dma-heap memory sharing for Mali.
All of the bridge is ASEbrahim's work; squashed only to carry it on this test branch.
Combined with #570 on this branch, a device draws through exactly one path:
- Adreno: Turnip, unchanged (checked first; the bridge setting is ignored there).
- PowerVR / Xclipse with the system HAL and a render node: the system-Vulkan path (#570).
- Anything else with the Setup toggle on (Mali): the bridge.
