Kyle Brenneman 638ef33fc7 EGL: Remove a few unused functions in egldispatchstubs.c.
Remove FindProcIndex, __eglSetDispatchIndex, and
__eglDispatchFindDispatchFunction from egldispatchstubs.c.

The dispatch indices are allocated and assigned during initialization, so none
of those functions are ever called.
