…h bundle downleveling This also allows terser to perform ECMA 6 level compress optimizations on the actual application bundles (non-script bundles) which can provide for further size improvements. Fixes angular#15507

Script bundles were not being subject to the terser mangle optimizations when using bundle down leveling.
This change also allows terser to perform ECMA 6 level compress and output optimizations on the actual application bundles (non-script bundles) which can provide for further size improvements. Also limits the parsing for optimizations of the script bundles to one step.
