  Re-land "Load correct libGLESv2 on Linux and Mac."
  
  Re-land fixes build to ensure commit_id is built before libEGL.
  
  libEGL was implicitly loading libGLESv2 on startup. This is bad
  because on platforms like Linux and Mac we could sometimes use the
  incorrect rpath. This in turn meant we needed workarounds like using
  "_angle" extensions to our shared objects to get the correct loading
  behaviour.
  
  Fix this by loading libGLESv2 dynamically in libEGL. We build the
  loader automatically from egl.xml. The loader itself is lazily
  initialized on every EGL entry point call. This is necessary because
  on Linux, etc, there is no equivalent to Windows' DLLMain.
  
  We also use an EGL.h with different generation options so we have the
  proper function pointer types. A README is included for instructions
  on how to regenerate EGL.h.
  
  The entry point generation script is refactored into a helper class
  that is used in the loader generator. Also adds the libGLESv2 versions
  of the EGL entry points in the DEF file on Windows. This allows them to
  be imported properly in 32-bit configurations.
  
  Also fixes up some errors in ANGLE's entry point definitions. Also
  includes a clang-format disable rule for the Khronos headers.
  
  This CL will help us to run ANGLE tests against native drivers.
