[gjs/mozjs91: 126/135] Use new Script private API

    Use new Script private API
    
    Setting Script privates has been removed from CompileOptions
    (see changeset below) in favor of a specific API for dynamic
    imports JS::[Set, Get]ScripePrivate (bug 1482153).
    
    Because we must manipulate the Script object itself we can no longer
    use the JS::Evaluate wrapper to set our environment chain and instead
    must use JS_ExecuteScript. Because our environment chain is
    "non-syntactic" (it doesn't come from any JS syntax) we have to specify
    this option. JS::Evaluate previously handled this for us in
    js/src/vm/CompilationAndEvaluation.cpp by passing ScopeKind::NonSyntactic
    in the override we used.
