  Re-land "Load entry points dynamically in tests and samples."
  
  Fixes the Android/ChromeOS/Fuchsia builds by using consistent EGL
  headers.
  
  This CL adds a dynamic loader generator based on XML files. It also
  refactors the entry point generation script to move the XML parsing
  into a helper class.
  
  Additionally this includes a new GLES 1.0 base header. The new
  header allows for function pointer types and hiding prototypes.
  
  All tests and samples now load ANGLE dynamically. In the future this
  will be extended to load entry points from the driver directly when
  possible. This will allow us to perform more accurate A/B testing.
  
  The new build configuration leads to some tests having more warnings
  applied. The CL includes fixes for the new warnings.
