Fix several WGL test failures. SimpleOperationTest.ClearAndSwap/ES2_WGL failed when run in isolation, since getGLWindow()->hasError() would report a previous error, instead of result of swapBuffers(). When running after an OPENGL test, swapBuffers() would clear the previous error, but that doesn't happen in isolation. The previous error is from loading WGL functions, some of which are expected not to be present. Clear the error in GetProcAddressWithFallback, but verify that there is no error entering it. This uncovers more errors in angle_perftests: DrawCallPerfBenchmark.Run/wgl DrawCallPerfBenchmark.Run/wgl_tex_change DrawCallPerfBenchmark.Run/wgl_vbo_change DrawElementsPerfBenchmark.Run/wgl_ushort They come from redundant calls when destroying a window. Fix this as well. Several more errors where uncovered by debug prints, fix those, too.
