Fix crash when calling certain gl APIs before initialization. ANGLE attempts to report an error if various APIs (incl. glClearStencil) are used before the context is set up. On Mac, when ANGLE attempts to report the error, if the egl platform is still uninitialized, it attempts to access NULL thread information via GenerateContextLostErrorOnCurrentGlobalContext. This leads to an assertion/crash. We can guard against this by calling egl::GetCurrentThread() first, which will do the lazy-initialization work that is needed. If egl is already initialized, this is harmless and very inexpensive.
