Antoine Doubovetzky 8a847a30e1 Replace ternary in assertGenericTypeAnnotationHasExactlyOneTypeParameter with typeParameterInstantiation attribute in parser (#35157 )

Summary:
Part of https://github.com/facebook/react-native/issues/34872:
> Create a new function typeParameterInstantiation in the [parsers.js file](https://github.com/facebook/react-native/blob/main/packages/react-native-codegen/src/parsers/parser.js) and add documentation to it. Implement it properly in the [FlowParser.js](https://github.com/facebook/react-native/blob/main/packages/react-native-codegen/src/parsers/flow/parser.js#L15) and in the [TypeScriptParser.js](https://github.com/facebook/react-native/blob/main/packages/react-native-codegen/src/parsers/typescript/parser.js#L15). Update the signature of [assertGenericTypeAnnotationHasExactlyOneTypeParameter](https://github.com/facebook/react-native/blob/main/packages/react-native-codegen/src/parsers/parsers-commons.js#L67) function to take the Parser instead of the language and use the new function in place of the [ternary operator ?:](https://github.com/facebook/react-native/blob/main/packages/react-native-codegen/src/parsers/parsers-commons.js#L83).

There are 3 things I'm not sure about:
1. The issue suggests to create a new function. For this case I believe an attribute is simpler. Is there a reason to prefer a function ?
2. To update the tests I had to create a mocked parser. I created a new file `parserMock` (I took example on [AnimatedMock](https://github.com/facebook/react-native/blob/main/Libraries/Animated/AnimatedMock.js)). Does it seem ok ?
3. I'm not sure what to add in the documentation of `typeParameterInstantiation`
