Revert "Hold host functions in var" (#26079)

sammy-SC · web-flow · commit 9b1423cc09c1 · 2023-01-30T17:23:02.000Z
Revert 353c30252. The commit breaks old React Native where `nativeFabricUIManager` is undefined. I need to add unit test for this to make sure it doesn't happen in the future and create a mechanism to deal with undefined `nativeFabricUIManager`. This is to unblock React sync to React Native.
