LibJS+LibWeb: Let WrapperGenerator deal with legacy_null_to_empty_string

Browse source 
This concept is not present in ECMAScript, and it bothers me every time
I see it.
It's only used by WrapperGenerator, and even there only relevant in two
places, so let's fully remove it from LibJS and use a simple ternary
expression instead:

    cpp_name = js_name.is_null() && legacy_null_to_empty_string
        ? String::empty()
        : js_name.to_string(global_object);
