AndroidTextInputNativeComponent: Make event properties ReadOnly

[empyrical]

Summary

This pull request makes properties of events' Flow types in AndroidTextInputNativeComponent be $ReadOnly.

This will make them more compatible with the callback types in TextInput.

Changelog

[Internal] [Changed] - Made properties of events' Flow types in AndroidTextInputNativeComponent readonly

Test Plan

yarn flow-check-ios and yarn flow-check-android both pass.

No regressions to running scripts/generate-rncore.sh have been noted.

Thanks! Can you run the codegen script as part of your test plan? Just checking that flow passes isn’t sufficient to know that the codegen supports these readonlys.

I think this is the script https://github.com/facebook/react-native/blob/master/scripts/generate-rncore.sh

[empyrical]

That script needs some modification to work (missing the positional argument "module spec name" to generate-tests.js) but I notice no difference in behaviour before or after this modification to AndroidTextInputNativeComponent.
