[flow-strict] Flow strict TextProps

[exced]

Related to #22100

Turn on Flow strict mode for TextProps.
I used ResponseHandlers type definition defined in Text.js.

I wanted to move ResponseHandlers type to TextProps and reuse it inside the file.
I know I could use $Shape<> to maybe keys but how do I elegantly maybe every values ?
Unless having a straightforward solution, I found it clearer to copy paste these types.

Test Plan:

• All flow tests succeed.

Release Notes:

[GENERAL] [ENHANCEMENT] [TextProps.js] - Flow strict mode

Hi @exced! Thanks for the help! I plan to combine those entries in the changelog to a single entry, so the changelog section in this PR is n/a. I'll make sure that once this PR lands, you're attributed for your contribution.

cc @empyrical, you two have similar types here for the responders between ViewProps and TextProps. Can you work together to figure out how these types should be consistent / share the same types?

[empyrical]

Maybe PanResponder can export a ResponderProps type that both View and Text can use the ...spread operator to make use of them?

[exced]

@empyrical Sounds good, do you want me to add it into this PR ?

[empyrical]

Actually I'm not sure if this can be done - it looks like Text and View don't all use the same responder props.

But for the type of event on your callbacks, you should import and use GestureState from PanResponder. I realize I improperly typed the event type in my PR and I will be updating them too. Then I think we are good on the responder types!

Sorry ignore that suggestion, I had that wrong because I was looking at something else 🤦‍♂️ Import PressEvent from CoreEventTypes and use that instead of SyntheticEvent<>

[exced]

No worries 😊

[exced]

@empyrical I replaced SyntheticEvent<> by PressEvent

[RSNara]

Awesome! 😁
