Extract the switch(configType) block from the buildSchema function into a new function in the parsers/utils.js file (#34992)

Summary:
This PR aims to extract  the switch(configType) block from the buildSchema function into a separate function in a shared file between typescript and flow. It is a task of https://github.com/facebook/react-native/issues/34872:
> This task is more advanced than the others. Extract the switch(configType) block ([Flow](https://github.com/facebook/react-native/blob/main/packages/react-native-codegen/src/parsers/flow/index.js#L82-L119), [TypeScript](https://github.com/facebook/react-native/blob/main/packages/react-native-codegen/src/parsers/typescript/index.js#L92-L129)) from the buildSchema function into a new function in the parsers/utils.js file and use it in the two functions. Note that the new function must accept some callbacks to wrapModule/ComponentSchema and to buildModule/ComponentSchema.
