test: use strict mode in global setters test

Trott · marco-ippolito · commit 11b82de7ed9c · 2025-03-06T13:38:18.000+01:00
test-global-setters.js was added in #26882 and hasn't been modified since. It appears that it avoids strict mode so that unscoped identifiers are treated as globals, but that's true in strict mode too. (In sloppy mode, an assignment to an undefined identifier will create a global, but that's not what this test does. In strict mode, those assignments will throw an error, which would seem to be what we would want.)
