Fix PAGImageView deadlock caused by animator update re-entering mutex

[leiyue123]

修复 iOS 和 OHOS 平台上 PAGImageView 因 animator update 回调重入 mutex 导致的死锁问题。

在 iOS 端，setBounds/setFrame 方法持有 imageViewLock 后调用 [animator update]，而 update 会同步回调 flush 再次尝试获取 imageViewLock，导致同一线程对非递归互斥锁的重入死锁。修复方式是将 [animator update] 调用移到锁作用域之外。

在 OHOS 端，onSurfaceCreated 同样存在持锁调用 _animator->update() 导致 onAnimationUpdate 回调重入 locker 的问题，采用相同策略修复。

handleSizeChanged就可以了，优化下函数名
