feat: New JS API for useCameraDevice and useCameraFormat and much faster getAvailableCameraDevices() (#1784)

* Update podfile

* Update useCameraFormat.ts

* Update API

* Delete FormatFilter.md

* Format CameraViewManager.m ObjC style

* Make `getAvailableCameraDevices` synchronous/blocking

* Create some docs

* fix: Fix HardwareLevel types

* fix: Use new device/format API

* Use 60 FPS format as an example

* Replace `Camera.getAvailableCameraDevices` with new `CameraDevices` API/Module

* Fix Lint

* KTLint options

* Use continuation indent of 8

* Use 2 spaces for indent

* Update .editorconfig

* Format code

* Update .editorconfig

* Format more

* Update VideoStabilizationMode.kt

* fix: Expose `CameraDevicesManager` to ObjC

* Update CameraPage.tsx

* fix: `requiresMainQueueSetup() -> false`

* Always prefer higher resolution

* Update CameraDevicesManager.swift

* Update CameraPage.tsx

* Also filter pixelFormat

* fix: Add AVFoundation import

You can use the helper function `parsePhysicalDeviceTypes` to convert a list of physical devices to a single device descriptor type which can also describe virtual devices:
```ts
console.log(device.devices)
// --> ["wide-angle-camera", "ultra-wide-angle-camera", "telephoto-camera"]
const deviceType = parsePhysicalDeviceTypes(device.devices)
console.log(deviceType)
// --> "triple-camera"
```
Always choose a camera device that is best fitted for your use-case; so you might filter out any cameras that do not support flash, have low zoom values, are not on the back side of the phone, do not contain a format with high resolution or fps, and more.

* The desired physical devices your camera device should have.
*
* Many modern phones have multiple Camera devices on one side and can combine those physical camera devices to one logical camera device.
* For example, the iPhone 11 has two physical camera devices, the `ultra-wide-angle-camera` ("fish-eye") and the normal `wide-angle-camera`. You can either use one of those devices individually, or use a combined logical camera device which can smoothly switch over between the two physical cameras depending on the current `zoom` level.
* When the user is at 0.5x-1x zoom, the `ultra-wide-angle-camera` can be used to offer a fish-eye zoom-out effect, and anything above 1x will smoothly switch over to the `wide-angle-camera`.
*
* **Note:** Devices with less phyiscal devices (`['wide-angle-camera']`) are usually faster to start-up than more complex
* devices (`['ultra-wide-angle-camera', 'wide-angle-camera', 'telephoto-camera']`), but don't offer zoom switch-over capabilities.
*
* @example
* ```ts
* // This device is simpler, so it starts up faster.
* getCameraDevice({ physicalDevices: ['wide-angle-camera'] })
* // This device is more complex, so it starts up slower, but you can switch between devices on 0.5x, 1x and 2x zoom.
* getCameraDevice({ physicalDevices: ['ultra-wide-angle-camera', 'wide-angle-camera', 'telephoto-camera'] })
