Codegen 123: add parser-primitive function for emitBoolProp (#37488)

Summary:
Part of #34872, Improving Codegen

Reduces code duplication by creating a helper function `emitBoolProp(name: string, optional: boolean)` in `parser-primitives.js`. Refactors the code from [Flow](https://github.com/facebook/react-native/blob/d8ced6f8953cd896471983714e722caf50783960/packages/react-native-codegen/src/parsers/flow/components/events.js#L37-L43) and [TypeScript](https://github.com/facebook/react-native/blob/d8ced6f8953cd896471983714e722caf50783960/packages/react-native-codegen/src/parsers/typescript/components/events.js#L47-L53) to utilize the new function.
