2.5.7: force-inline detail::parse_array_index (#5891)

Browse Source 
Moving parse_array_index out of json_pointer stopped clang from inlining it
into the pointer resolution (JsonPointerAt/citm_catalog +17%,
JsonPointerAt/twitter +8%); JSON_HEDLEY_ALWAYS_INLINE restores the baseline.

@note this function never throws; json_pointer::array_index(), the callers that
must not throw, and the json_view pointer resolution build on it instead
of each re-implementing the RFC 6901 digit rules and the range check
@note force-inlined: as a free function template it is no longer inlined into
the pointer resolution, which makes JsonPointerAt up to 17% slower (#5891)
