This CL adds Fuchsia-specific implementations to the following classes: dawn_native::vulkan::external_memory::Service dawn_native::vulkan::external_semaphore::Service The implementation is based on two Fuchsia Vulkan extensions that are provides by the vulkan_fuchsia_extras.h header (i.e. are not upstreamed to Khronos yet, but used/provided by the Fuchsia platform): VK_FUCHSIA_external_memory VK_FUCHSIA_external_semaphore Their details are similar to VK_KHR_external_XXXX_fd, but uses Zircon handles instead of file decriptors.
