Summary: Allow modifying iOS image cache limits. Currently the image cache imposes some strict limits: [NSCache.totalCostLimit](https://developer.apple.com/documentation/foundation/nscache/1407672-totalcostlimit?language=objc) of 20MB. Single Image Size Limit of 2MB (bitmap size). This may not be enough for applications that make heavy use of images. With this commit it is possible to fine tune them to the applications need. This can be set for example in the App Delegate with: ```objc RCTSetImageCacheLimits(4*1024*1024, 200*1024*1024); ``` This would increase the single image size limit to 4 MB and the total cost limit to 200 MB. ## Changelog [iOS] [Added] - Allow modifying iOS image cache limits Pull Request resolved: facebook#33554 Test Plan: There is no easy way to test this except adding the above snippet and checking via break points that the new limits are used.
