3.17.1 loading CocosBuilder .csb file becomes extremely slow

[EricDDK]

when the textureSize is 546,using time is 18400 ms.
In 3.17,it's correct.
I'm blowsing the changing from 3.17 to 3.17.1.
Of course I can submit the res of .csb file.

ValueMap dict = FileUtils::getInstance()->getValueMapFromFile(fullPath);
this function in void SpriteFrameCache::addSpriteFramesWithFile(const std::string& plist) will use more than 70ms every time in for loop.

I forgot something that the sprite frames are in memory.

How long does it take to load 546 textures in 3.17? @EricDDK

[EricDDK]

@PatriceJiang 18000+ms in vs 2015 debug module
You can see the indicator in my picture.

[EricDDK]

@PatriceJiang it use 120 ms in 3.17.

[PatriceJiang]

Can you upload a plist with images files which take 70 ms to load? Most test cases I have tried only takes around 3ms.

[EricDDK]

@PatriceJiang I change back the CCSpriteFrameCache.h and CCSpriteFrameCache.cpp to 3.17.
The bug is fixed.

I gave you the lua project which I test.
New a 3.17.1 lua project and replace the src and res.

I make a PR at #19269, please check if your problem is fixed.
