  Tests: Use eglGetPlatformDisplay()
  
  From the EGL 1.5 spec:
  
    Appendix F
    Version 1.5
  
    EGL version 1.5 was voted out of the Khronos Technical Working Group
    on January 31, 2014, and formally approved by the Khronos Board of
    Promoters on March 14, 2014.
    EGL 1.5 is the sixth release of EGL. It introduces the following new
    features (the EGL extension(s) each feature is based on are also shown
    parenthetically):
    * Platform support:
      – Providing a mechanism for support of multiple platforms (such as
      window systems or offscreen rendering frameworks) in a single EGL
      implementation at runtime (EGL_EXT_platform_base).
  
  Many tests use eglGetPlatformDisplayEXT() which is provided by the EGL
  extension EGL_EXT_platform_base. With the promotion of the
  EGL_EXT_platform_base functions to core EGL in version 1.5 and ANGLE
  supporting EGL 1.5 (as of at least 2019), update the calls to use
  eglGetPlatformDisplay().
  
  This is in preparation for running the ANGLE end2end tests in Android,
  which only exposes the EGL 1.5 functions, and not the
  EGL_EXT_platform_base functions.
  
  Bug: b/391967165
  Test: angle_end2end_tests
