flutter/engine#50076 added a mechanism to store impeller::Paths in the display list alongside the Skia Path. On an example application in #131345 (comment) , this mechanism is regressing performance due to the additonal cost of heap allocation/deallocation of the storage data. Because the Paths are recreated every frame, it does not benefit from the cache.

The additional dtor time in the profile is due to free-ing the cacheable paths. Perhaps we can get some of this performance back by inlining the vector allocation into the Path::Data object, thereby reducing the total heap allocations?
