  Reland "EGL: GLES: Implement GL_EXT_protected_textures"
  
  This is a reland of 6210a9b34a721df2c84cf69170ad9bf7ba40e4aa
  This removes changes in gl backend.
  
  Original change's description:
  > EGL: GLES: Implement GL_EXT_protected_textures
  >
  > Implement EGL_EXT_protected_content Images
  > Add protected member to Images and Textures
  > Add error when creating objects if not supported or
  > does't match native buffer
  > When creating siblings pass protected state
  > Add extension caps
  > Add Validation
  > Add GetTexParameter and SetTextparameter
  > Add protected to Texture and state
  > Expand tests for images and textures
  >
  > Test: angle_end2end_test --gtest_filter=EGLProtectedContentTest
  >
  > Bug: angleproject:3965
