Frank Denis 0747591c3d Add std.crypto.utils.timingSafeCompare
A little function to complement the existing crypto.utils.timingSafeEql
function with a way to compare large numbers serialized as arrays.

This is useful to compare nonces and to check that group elements are
in canonical form.

Absence of side channels remains a best effort, reusing the common
pattern we use elsewhere.
