  EGL: Update EGL headers/xml
  
  The new EGL headers introduced 'EGL_NO_X11' which we could use
  for ANGLE vulkan display/headless backend.
  
  Changes in CL:
  
  1. Updated include/EGL/egl*.h and scripts/egl.xml based on latest
     EGL repo: https://github.com/KhronosGroup/EGL-Registry
     Note: local modifications to the file were preserved in
     eglext.h, search keyword 'eglext_angle.h' for detail
  2. run scripts to update entry_points/loader
     scripts/generate_entry_points.py
     scripts/generate_loader.py
     scripts/run_code_generation.py
  3. Update ANGLE code on API 'eglSwapBuffersWithDamage'
  4. Format with 'git cl format'
