Subject: [Lightbox] Open animation (#6159)

* Measure all rects for embeds

* Measure avi rects too

* Animate lightbox in and out

* Account for safe area in the animation

* Tune spring times

* Remove null checks for measurements

* Remove superfluous view

* Block swipe while opening

* Interpolate width/height on native side for Android

* Make it fast by animating only affine transforms

* Fix tall image final state

The initial animation frame is still off on both platforms.

* Try to squeeze perf

* Avoid blank images during animation on iOS

* Fix bad rebase

* Fix a huge memory issue due to expo/expo#24894

* Fix last frame flash

* Fix thum dim calculation for tall images
