Correctly create the first modal state (#52835)

Summary:
There is currently a bug with Modals with New Architecture where the first frame is rendered incorrectly, specifically not accounting for all the vertical insets (only the status bar). This fixes it.

Specifically:
1. I've removed the caching of the statusbar height from `ReactModalHostView` as that was not working correctly. Sometimes the value returned `0` meaning that it was not yet computed when Fabric was asking for it. In the updated implementation we now query `FabricUIManager` given the `surfaceId` of the modal.
2. I've modified the logic to account for all the vertical insets, not just the status bar.

## Changelog:

[ANDROID] [FIXED] - Correctly account for insets on first render of Modals on New Arch


Test Plan:
Tested on Marketplace Location Picker and the picker is still working correctly:
