Fail Vulkan surface creation if window has context

OpenGL / OpenGL ES cannot share presentation on a window with Vulkan.
This adds an error to `glfwCreateWindowSurface` when it is called on a
window without the GLFW_CLIENT_API hint set to GLFW_NO_API.  This
prevents undefined bahevior and hard to debug crashes.

Fixes #1194.
Closes #1205.
