move getEventArgument function into parsers-commons.js (#37133)

Summary:
[Codegen 116] This PR attempts to extract the logic of `getEventArgument` function from the following locations :
- `parsers/flow/components/events.js`
- `parsers/typescript/components/events.js`
since they are the same and move the function to `parsers/parsers-commons.js` as requested on #34872

## Changelog:

[Internal] [Changed] - Move `getEventArgument` to parser-commons and update usages.

Pull Request resolved: #37133

Test Plan: Run `yarn jest react-native-codegen` and ensure CI is green
