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.

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.
