fix: calculate values of useHeaderHeight natively #1802

Description

Currently, useHeaderHeight() hook returns default values, hard-coded in JS code. It uses react-native-safe-area-context under the hood to calculate top inset of the status bar and returns a header height 56 (for android) or 64 (for iOS).
This PR introduces new useAnimatedHeaderHeight hook that calculates header height on each layout change.

Changes

  • Added support for calculating header height dynamically on the old / new architecture for Android and iOS.
  • Added event that is being executed on header height change.
  • Added new useAnimatedHeaderHeight hook for getting header height that is being calculated dynamically.

After

Test code and steps to reproduce

See Test1802 in TestsExample or FabricTestExample.
There's also Test1802b included. It's a reproduction for an issue #1671 which shows that issue should be fixed after this change.

Will this also mitigate the issue with the jumping header on Android when using bottom tabs?

Hi @hirbod, I think it should, but as this PR is still in an early state I cannot guarantee that. If this problem is strictly related to the value that is represented by the useHeaderHeight(), I'll try to find the solution for this bug and test it in this PR additionally 🎉

That’s such good news @tboba, this dynamic calculation of the header size works also correctly on iOS modals?

@outaTiME I looked onto that and it looks like header height is not being calculated on full screen modal - I already know why! I'll make a patch tomorrow for that 👍

@tboba great work, thank you!

I just tested the new useHeaderHeight with a header with a search bar in iOS. Returning value doesn't include the height of the search bar. It would be great also to cover this case.

Hi @ha3, thanks for letting us know! ❤️

It looks like use(Re)animatedHeaderHeight calculates the header correctly (modifying the test a bit I can confirm this hook is returning correct value - transformY for Animated.Value puts FullWindowOverlay underneath the header).

However, as I tested useHeaderHeight it seems that search bar is indeed not taken into account with calculations.

As we're now thinking about changing the implementation of useHeaderHeight completely, we will take care of it some day, but we won't fix this in this PR. Stay tuned 🙏

…ismisses

Finally, a long-debated topic has met its end. I've managed to dive deeper how NativeStackView is currently storing values and reduces the amount of calls to `calculateHeaderHeightIsModal` on iOS. In case when bugs related to the `use(Re)animatedHeaderHeight` hook will occur in the future, we should consider looking into this commit in case when there will be a need to increase amount of calls to this method.
This change has been tested on ScreensExample/TestsExample iOS environment, including nested stacks.

/cc @kkafar @WoLewicki could you please take a quick look into those changes? I've removed 3 of 5 calls to calculateHeaderHeight that were recalculating unnecessarily header height on modal dismissals and changed a bit the structure of animatedHeaderHeight 🙇

## Description

Currently, on Android side it looks like we're using `useSafeAreaInsets`
hook from `react-native-safe-area-context` improperly. This hook is
sending proper status bar height only if there's option
`statusBarTranslucent` set to true. Thus, we should use y-axis position
of the frame - `useSafeAreaFrame` is giving us this option with its `y`
value.

This change is a part of ongoing work in Pull Request #1802 that
implements `use(Re)animatedHeaderHeight` hook.

## Changes

- Added a statement that checks if `statusBarTranslucent` option is set
to true for Android.
- Refactorized a logic for getting status bar height and moved it to new
function.

## Screenshots / GIFs

### Before

<img width="1505" alt="Screenshot 2023-08-21 at 10 22 13"
src="https://github.com/software-mansion/react-native-screens/assets/23281839/b504115f-5fc6-44d7-b82b-9a49ac19be86">

We can see the correct value (from `react-native-safe-area-context`
perspective) is being reported wrongly by useSafeAreaInsets after
reporting initial inset. This probably occurs because of the ViewGroup
being layout after sending initial metrics.

### After

iOS devices are not impacted because of this change.
You can use `Test1844` to test the changes.

I'm leaving green for the code changes, however I haven't tested the final version yet. I'll do it soon.
