vulkan: Mark external memory textures as preinitialized Textures initialized from external memory objects should be considered preinitialized so that they're not cleared on first access with robust resource init. This is essential for Vulkan-GL (WebGPU-WebGL) interop on Linux where Skia or Dawn could be first used to render into a VkImage backed by an external memory object, and a GL texture is created lazily on first GL access. This CL also includes an end-to-end test for such interop, and changes to support that test: 1) Add writePixels() to VulkanHelper to upload pixels to a VkImage 2) Detect external memory / semaphore extensions when VulkanHelper is initialized from ANGLE. 3) Allow importing external memory object that's larger than VkImage size requirements.
