feat(windows): updates for RNW 0.63 (react-native-camera#2960)

Build:
* Updated huycn.zxingcpp.winrt to v1.1.0, enables ARM64 build on RNW >=
  0.61
* Updated ReactNativeCameraCPP.sln with RNW 0.63 dependencies
* Added ReactNativeCameraCPP62.sln for building against RNW 0.62
* Cleaned up ReactNativeCameraCPP61.sln for building against RNW 0.61

ReactNativeCamera RNCamera component:
* Passing unspecified maxDuration to recordAsync no longer stops
  recording immediately

Documentation:
* Updated installation docs for RNW 0.63 auto-linking

Closes react-native-camera#2942, react-native-camera#2944

-# React Native Camera (Windows)
-
-React Native Camera is currently maintained for React Native Windows (RNW) >= 0.61.
-
-There are two implementations of `react-native-camera` in this folder:
-
-1. _ReactNativeCameraCPP_ is the currently maintained implementation:
-   1. Use _ReactNativeCameraCPP_ for RNW >= 0.62.
-   2. Use _ReactNativeCameraCPP61_ for RNW 0.61.
-2. _RNCamera_ is a legacy implementation for `[email protected]`. It is no longer maintained.
-
-## Why all the different versions?
-
-RNW was originally implemented in C#, where development stopped at version 0.59. _RNCamera_ is the version of React Native Camera written in C# against that (now "legacy") RNW.
-
-RNW was then rebuilt from scratch in C++, and version 0.61 was the first release to support native community modules. _ReactNativeCameraCPP_ is the version of React Native Camera written in C++ against the current RNW.
-
-RNW 0.62 brought a variety of build improvements, but now requires both Visual Studio 2019 and a newer Windows SDK. So while the native module APIs are 99% forward-compatible, it's currently necessary to maintain a separate `ReactNativeCameraCPP61.vcxproj` project for RNW 0.61 users. The `ReactNativeCameraCPP.vcxproj` project targets RNW >= 0.62 users.
-
-# Local Development Setup (RNW >= 0.62)
-
-In order to work on _ReactNativeCameraCPP_, you'll need to install the [Windows Development Dependencies](https://microsoft.github.io/react-native-windows/docs/rnw-dependencies).
-
-In addition, `react-native-camera` targets React Native 0.59 and doesn't include React Native Windows as a dependency. So in order to build _ReactNativeCameraCPP_ locally you'll need to temporarily upgrade the development dependencies:
-
-```
-yarn upgrade react-native@^0.62.2
-yarn add react-native-windows@^0.62.0 --dev
-```
-
-Now you should be able to open `ReactNativeCameraCPP.sln` in Visual Studio and build the project.
-
-> _Note:_ In order to test your code changes don't break RNW 0.61, you'll want to do the above steps but targeting RN/RNW 0.61, and using `ReactNativeCameraCPP61.sln`.
