Reland: Don't export ANGLE platform methods. These functions are loaded through eglGetProcAddress. We don't need to export these extra symbols and increase our binary size. Temporarily still export them on Android. The Android platform loads them using dlsym [0] to detect if a driver is ANGLE or not.
