[FEATURE] Add ECMAScript-like MaxSafeInteger constant #2136
Description
The doc for maxflint is currently wrong (in the process of being fixed), this lead to me confusing this constant with the "max safe integer" one from (for example) ECMAScript (defined as the max integer floating value that does not share a bit-representation with any other integer floating value, that is effectively maxflint - 1).
Having the later in EVE too would prevent future confusion between the two.
