Build and deployment performance

GitHub PR 5304: Add support for producing a ProGuard mapping.txt file to the build system. This file can be used by users to remove this warning:
```
"This App Bundle contains Java/Kotlin code, which might be obfuscated."
```
... when uploading packages to the Google Play Store.

In order to opt-in to this behavior, set the AndroidProguardMappingFile MSBuild property in your project file to the path of the file you want generated:
```
<PropertyGroup>
  <AndroidProguardMappingFile>$(OutputPath)\mapping.txt</AndroidProguardMappingFile>
</PropertyGroup>
```
