Unify findComponentConfig return statement (#36446)

Summary:
> [Codegen 100] Create a createComponentConfig function in the parser-commons.js file. It takes the foundConfig and the commandTypeNames as parameters and returns the component config object. Extract the return statements ([Flow](https://github.com/facebook/react-native/blob/main/packages/react-native-codegen/src/parsers/flow/components/index.js#L115-L126) [TS](https://github.com/facebook/react-native/blob/main/packages/react-native-codegen/src/parsers/typescript/components/index.js#L116-L127)) and use those implementations in that function.

Part of Issue https://github.com/facebook/react-native/issues/34872

In case I should already add better typing I can update the PR while clarifying the type definitions.

## Changelog

[INTERNAL] [CHANGED] - Move the return statement of `findComponentConfig` to `parsers-commons.js` merging Flow and TS implementation.

Pull Request resolved: https://github.com/facebook/react-native/pull/36446

Test Plan: `yarn lint && yarn run flow && yarn test react-native-codegen`
