use package from activity context to support compose

[GoodSir42]

this fixes #2371 by using the bundle ID from the activity as a fallback. You might make this the default package ID and just treat this PR as a general hint in which direction to go. let me know if you need any further input on this matter.

It would be absolutely great to have compose support as I personally like the UI framework a lot :)

@GoodSir42 thanks for providing the PR! Is it intentional that you use the "fallback" immediately on the first level of recursion? Wouldn't it be more backward compatible to call ParseRecursive and afterwards use the _structure.ActivityComponent.PackageName if no PackageId was found?

[GoodSir42]

@PhilippC yes, that actually sounds far more reasonable 😄 C# is not my strong language and as I said it's probably best to use the PR as an inspiration with more knowledge about the project rather than merging it as is.
The general idea was to determine the fallback bundle ID if nothing else could be found rather than androidapp://

[GoodSir42]

I updated the PR so that the fallback will only be used if no information could be parsed from the structure
