Advertise the VK_EXT_shader_stencil_export extension.

This is supported by Mac GPU Family 2 starting on macOS 10.14, and Apple
GPU Family 5 starting on iOS 12.

Supporting this is a bit tricky. Because only some devices support this
extension, we now have to keep track of supported device extensions per
device.
