Implement callFunctionOnModule on BridgelessCatalystInstance (#56804)

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/56804

Implement `BridgelessCatalystInstance.callFunction` using the existing `ReactHostImpl.callFunctionOnModule` so callers that go through `CatalystInstance` (rather than directly through `JavaScriptModule` proxies) work in bridgeless mode.

While here, propagate nullability of `args` through the call chain. `InvocationHandler.invoke` is documented to pass `null` when the proxied method has no parameters, and the existing `Arguments.fromJavaArgs(args)` would NPE in that case. The JNI layer substitutes an empty `folly::dynamic::array()` when `args` is null, so the JS call still has a well-formed argument list.

Changelog: [Android][Fixed] JSModule method without args are correctly dispatched
