Implement Vulkan API for reading the display's size
* magma: Add Magma APIs for reading the display size. Add public API
in magma.h and add driver API in msd.h. Add IPC plumbing (an
ioctl) for reading the display size.
* drivers/gpu/msd-intel-gen: Implement the driver API by reading the
display size from the register state.
* third_party/mesa: Implement the Vulkan API --
vkGetPhysicalDeviceSurfacePresentModesKHR() -- in terms of the
Magma public API.
Note that the vkcube demo already uses that Vulkan API, so it will
start using the actual display size (rather than a default) after this
change.
