[flame_tiled] Tile flip makes performance issue.

# Current bug behaviour
As I wrote in #1614, the FPS of the`tiledComponent` is very close to 0 before #1637.
And after #1637, The most of performance issue is gone so I felt there is no performance issue.

But I found some maps which have flips has lower FPS than others that don't have any flip.

So I tried to turn off flips forcefully by manipulating the following line to investigate what is the problem.
I changed `tile.flips` to `Flips.defaults()` and the performance issue is gone.
So I carefully predict that the performance is affected by flips.

It seems some performance issue is resolved but some of them still remains.

# Expected behaviour
- Fix performance issue when using flips.

# Steps to reproduce
- I should investigate more for this
- **I found it occurs only on IOS**

Start at packages/flame_tiled/lib/src/renderable_tile_map.dart around line 169, where tile.flips is involved in rendering. Profile comparable flipped and unflipped maps on iOS, then identify and verify the performance regression; done means flipped tiles no longer cause the reported FPS drop.
