Summary:
Changelog: [Internal]

# Problem

We call `_state->updateState` anytime safe area insets changes.
Once that is called, `_state` still holds old value, so when we check whether there is big enough of a difference, we are actually checking it against old value of state until `updateState` is called from MountingManager.

This causes `_state->updateState` to be called dozens of times (I measured 47, with this diff it fell to 22) when displaying a safe area view inside Modal.

# Solution

Create new ivar `_lastPaddingStateWasUpdatedWith` where we store last padding that was sent through `_state->updateState` and compare new inset with this value instead of last value stored in state.
