refactor: new way for handling insets

[kirillzyusko]

📜 Description

Setup onApplyWindowInsetsListener that manages systemBars and navigationBar on rootView to get correct and constant insets.

💡 Motivation and Context

If we setup onApplyWindowInsetsListener on EdgeToEdgeReactViewGroup, then sometimes insets are including keyboard size (it's is 0, 1225 (top, bottom) instead of expected 144, 84).

I discovered that if we setup onApplyWindowInsetsListener on rootVIew - in this case insets are always stable. So I reworked this part (worth to note that onApplyWindowInsetsListener that detects keyboard size changes still should listen to EdgeToEdgeReactViewGroup because otherwise it's not working).

It fixes a problem with content jump, however the old approach (setting padding for action_bar_root) is not working anymore - instead we should apply margin. Last, but not least - we should setup it asynchronously, because if we setup it in onAttachedToWindow/init then it'll add undesired padding:

Area in blue - undesired margin

Fixes #51

📢 Changelog

Android

• apply margin to action_bar_root instead of padding;
• for managing paddings setup onApplyWindowInsetsListener on rootView, keep onApplyWindowInsetsListener on EdgeToEdgeView just for detecting keyboard size changes;
• setup onApplyWindowInsetsListener on rootView asynchronously (to avoid unnecessary margin on mount);
• added ThemedReactContext extension that returns rootView;

🤔 How Has This Been Tested?

Tested (fabric/paper) on:

• Pixel 7 Pro (Android 13);
• Redmi note 5 Pro (Android 9);

I don't think we should set the margin here because it will push all the content down which kind of defeats the purpose of setting the status bar to translucent, but correct me if I'm wrong because I didn't really investigate this. I believe this is causing a regression where all my content is being pushed below the status bar even when set to translucent

@thespacemanatee yes, most likely this PR caused your regression. Let's move all our conversation to the issue that you opened 👀
