  tests: Add GetEglPlatform()
  
  Testing the system EGL library was recently added to ANGLE's end2end
  tests, breaking the assumption that the tests were interacting with the
  ANGLE EGL library directly.
  
  Many EGL end2end tests call eglGetPlatformDisplay() with the platform
  value EGL_PLATFORM_ANGLE_ANGLE. However, Android only allows
  EGL_PLATFORM_ANDROID_KHR, rejecting all other values (returning
  EGL_NO_DISPLAY).
  
  Add GetEglPlatform() to return the platform value to pass to
  eglGetPlatformDisplay(), based on things like the driver being tested
  and the OS the tests are running on. Currently, this only supports
  returning EGL_PLATFORM_ANDROID_KHR for SystemEGL+Android, and
  EGL_PLATFORM_ANGLE_ANGLE for everything else.
