[upstream][paper] Fix crash when statically enabling wantsUpdateLayer for View component

Summary:
This diff fixes an invariant that wasn't valid anymore after having enabled `wantsUpdateLayer` statically for the View component in Fabric.

`RCTUIView` in RCTUIKit enables `wantsUpdateLayer` only if the instance implements the `displayLayer:` method. Because the View component always wants to have `wantsUpdateLayer` enabled, the assumption that `displayLayer:` exists wasn't valid anymore.

This diff only calls the `displayLayer:` method if the instance effectively responds to it. To avoid a perf hit on the check, we only test for it in the initialization and cache the result.

Test Plan:
* Run the Cosmo app
```
~/fbsource/xplat/arfx/cosmo/mac/run.sh
```
