Dmitrii Kanatnikov 18e474f522 fix(zone.js): zone.js toString patch should check typeof Promise is function (#38350) ...

Close #38361

zone.js monkey patch toString, and check the instance is `Promise` or not by using `instanceof Promise`,
sometimes when Promise is not available, the `instanceof` operation fails
and throw `TypeError: Right-hand side of 'instanceof' is not an object`
this PR check `typeof Promise` equals to function or not to prevent the error.
