Add architecture info to the 0141 warning

[grendello]

Partial fix for #9544 to make
the warning more informative. Architecture information is necessary as
the nuget in question might have the same library for various
architectures.

Do we have the full path to the .so file? It seems like we could simply put that in the error message and that's it?

If it's from a NuGet package, you will know what package and version from the file path.

I considered that, but I figured most people won't find it actionable anyway. They most likely don't maintain the nuget,
so the full path is just cognitive noise for them. With the library name + architecture then can, however, go to the nuget
authors and just let them know about the two dateails.

[jonathanpeppers]

The full path to the file is more informative than <unknown>, though, right?

[jonathanpeppers]

Could we use the overload for LogCodedWarning where you pass the file path in, and put 0 for line number:

• https://github.com/dotnet/android-tools/blob/60fae1924e2d71f31dc1ed05f7346fd7874d6636/src/Microsoft.Android.Build.BaseTasks/MSBuildExtensions.cs#L132

This would include the file, and if you double-clicked the error in an IDE it would open the file.

It is, but it also potentially leaks information about the user's environment, if shared (operating system, user login name), since it's going to be in the nuget cache.
The <unknown> part is something that needs a fix too, I imagine it should be possible to get that information from transient dependencies.

Can we also update the verbiage to be less scary:

warning XA0141: NuGet package 'Xamarin.GooglePlayServices.Vision.Face.Contour.Internal' version '116.1.0.19' contains a shared library 'arm64-v8a/libface_detector_v2_jni.so' which is not 16KB aligned. Google may require 16KB aligned libraries in the future. See https://developer.android.com/guide/practices/page-sizes for more details.

[grendello]

@jpobst we can change the wording, but there's no "may" about it - they will require that alignment.

Linux build fails with

Workload installation failed: Version 35.99.0-ci.pr.gh9547.38 of package microsoft.android.sdk.linux is not found

@pjcollins @jonathanpeppers any idea what might be causing it?

This is a weird issue where the source in the target branch appears to have been updated between when the mac build ran and the linux build ran -- we have packages on the PR with different versions:

Did the linux build initially fail and re-run? I think we'll need to just kick off a new build

/azp run

[azure-pipelines]

Azure Pipelines successfully started running 1 pipeline(s).

This failing check will continue to show on the PR from the old build since we're rebuilding the same commit, and it can be ignored in favor of the new build:

Xamarin.Android-PR (Linux Tests Linux > Tests > MSBuild)

Yep, I restarted it two times I think. Let's hope it works fine now, thanks for looking into it :)
