feat: Complete iOS Codebase rewrite (#1647)
* Make Frame Processors an extra subspec

* Update VisionCamera.podspec

* Make optional

* Make VisionCamera compile without Skia

* Fix

* Add skia again

* Update VisionCamera.podspec

* Make VisionCamera build without Frame Processors

* Rename error to `system/frame-processors-unavailable`

* Fix Frame Processor returning early

* Remove `preset`, FP partial rewrite

* Only warn on frame drop

* Fix wrong queue

* fix: Run on CameraQueue again

* Update CameraView.swift

* fix: Activate audio session asynchronously on audio queue

* Update CameraView+RecordVideo.swift

* Update PreviewView.h

* Cleanups

* Cleanup

* fix cast

* feat: Add LiDAR Depth Camera support

* Upgrade Ruby

* Add vector icons type

* Update Gemfile.lock

* fix: Stop queues on deinit

* Also load `builtInTrueDepthCamera`

* Update CameraViewManager.swift

* Update SkImageHelpers.mm

* Extract FrameProcessorCallback to FrameProcessor

Holds more context now :)

* Rename to .m

* fix: Add `RCTLog` import

* Create SkiaFrameProcessor

* Update CameraBridge.h

* Call Frame Processor

* Fix defines

* fix: Allow deleting callback funcs

* fix Skia build

* batch

* Just call `setSkiaFrameProcessor`

* Rewrite in Swift

* Pass `SkiaRenderer`

* Fix Import

* Move `PreviewView` to Swift

* Fix Layer

* Set Skia Canvas to Frame Host Object

* Make `DrawableFrameHostObject` subclass

* Fix TS types

* Use same MTLDevice and apply scale

* Make getter

* Extract `setTorch` and `Preview`

* fix: Fix nil metal device

* Don't wait for session stop in deinit

* Use main pixel ratio

* Use unique_ptr for Render Contexts

* fix: Fix SkiaPreviewDisplayLink broken after deinit

* inline `getTextureCache`

* Update CameraPage.tsx

* chore: Format iOS

* perf: Allow MTLLayer to be optimized for only frame buffers

* Add RN Video types

* fix: Fix Frame Processors if guard

* Find nodeModules recursively

* Create `Frame.isDrawable`

* Add `cocoapods-check` dependency
