Closure requires @nocollapse on Ivy definition static fields in order to not convert them to standalone constants. However tsickle, the tool which would ordinarily be responsible for adding @nocollapse, doesn't properly annotate fields which are added synthetically via transforms. So this commit adds @nocollapse by applying regular expressions against code during the final write to disk. PR Close #25775
