Use compiler-safe Reanimated get/set APIs (#6391)

Browse Source 
* Convert lightbox to get/set

* Work around software-mansion/react-native-reanimated#6613

* Use get/set in more places

* Port MainScrollProvider to get/set

* Port more to get/set

* Port composer to get/set

* Remove unnecessary thread hops in composer

* Port more things to get/set

* Convert more to get/set, remove redundant runOnJS

* Convert remaining cases to get/set
