Migrating much of EGL validation to use existing macros.

Added new Validate* functions for eglDestroySurface(),
eglDestroyContext(), eglWaitNative() functions.

This continues the EGL validation refactor begun with SwapBuffers.
Following similar pattern used there, but putting this out as an
intermediate change to verify that code looks good and is going in the
desired direction.
