Add error reporting examples to rn-tester turbo modules (#36729)

Summary:
This PR is adding examples of Turbo Modules functions throwing runtime exceptions and asserts. This should make it easier to collaborate and develop the error reporting for a new architecture that is being discussed in the React Native New Architecture Working Group -> https://github.com/reactwg/react-native-new-architecture/discussions/122.

I'm not sure what return type should be used for the JS function returning `Promise<void>` in Cxx, I used [`AsyncPromise<jsi::Value>`](https://github.com/facebook/react-native/pull/36729/files#diff-9cebc75f48fd35fd6fef71138f98dfd0ba28a754b2aab0d6fe44fd685f74ce16R135), what would you use, I've not found `void` type to use?

### Added functions

The table shows the current behavior.

<table>
<tr>
	<td> Function
	<td> Description
	<td> Turbo Module
	<td> Cxx Module
<tr>
	<td> voidFuncThrows
	<td> function with return type void throws a runtime exception
	<td> platform error no JS stack trace
	<td> JS error no native stack trace

	<td> function with return type object throws a runtime exception
	<td> JS error no platform stack trace

[INTERNAL] [ADDED] - Error reporting examples in rn-tester turbo modules

Pull Request resolved: https://github.com/facebook/react-native/pull/36729

Test Plan:
This PR doesn't change any RN behavior. Only shows the current state by adding an example to rn-tester.

I'm happy to add these examples to the unit/integration test, just point me to where would be a good place.
