Native bindings to the ANDROID_recordable extension.

Android supports a number of different ANativeWindow implementations that can be used to create an EGLSurface. One implementation, which records the rendered image as a video each time eglSwapBuffers gets called, may have some device-specific restrictions. Because of this, some EGLConfigs may be incompatible with these ANativeWindows. This extension introduces a new boolean EGLConfig attribute that indicates whether the EGLConfig supports rendering to an ANativeWindow that records images to a video.
