[builds/unix] Do not use autoconf SIZEOF. * builds/unix/ftconfig.h.in [FT_USE_AUTOCONF_SIZEOF_TYPES]: Removed. * builds/unix/configure.raw: Remove AC_CHECK_SIZEOF and update. After this commit, autoconf builds will fully rely on <limits.h> rather than falling back on it if AC_CHECK_SIZEOF failed for some reason. There is a risk that misconfigured cross-compilation might have wrong headers. Note that Meson and CMake builds always relied on <limits.h> for sizes and availability of integer types.
