Fix SVC Validator for Box Shadow and filter (#46454)

Summary:
Pull Request resolved: #46454

The SVC Validator have no idea on how to process a simple NSArray *.

With this change, we are creating two named types for the NSArray:
* BoxShadowArray
* FilterArray
To create unique types that we can reference in JS.

We are then enhancing the `getProcessor` function to return the proper processor when those types are found in the NativeViewConfig

## Changelog:
[iOS][Fixed] - Fixed warnings when validating SVC

## Facebook:
This change is OTA safe: even when we ship the JS before the native code, the new cases in the switch will be never hit, similarly to the situation we have right now.

As soon as the native code is shipped, the new cases will start get hit and the wrning will disappear
