Vulkan: Inform frontend when new buffer is allocated When a buffer is mapped with GL_MAP_INVALIDATE_BUFFER_BIT while it's currently in use, the Vulkan backend will allocate a new buffer, map it, and return the pointer to the new buffer. This was missing a call to inform the frontend that a new buffer was allocated, causing the old buffer data to be accessed in subsequent draw calls. The fix is to add a onStateChange(angle::SubjectMessage::SubjectGhosted) call when the new buffer is allocated, to inform the frontend.
