libvixl: Correct build failures on NetBSD

Browse Source 
Ensure that C99 macros are defined regardless of the inclusion order of
headers in vixl. This is required at least on NetBSD.

The vixl/globals.h headers defines __STDC_CONSTANT_MACROS and must be
included before other system headers.

This file defines unconditionally the following macros, without altering
the original sources:
 - __STDC_CONSTANT_MACROS
 - __STDC_LIMIT_MACROS
 - __STDC_FORMAT_MACROS
