[DO NOT MERGE] TFM net9.0

[moljac]

Dogfooding net9.0 only TFM for AndroidX (AX) bindings.

It is to be determined if and when to merge. Thus DO-NOT-MERGE in title and label + draft status.

Some metadata had to be fixed. And some APIs have changed and this needs some investigation

GPS-FB-MLKit PR is Work in Progress (WIP).

Does this change any of the generated binding API's?

Probably. Not sure yet. There were some Metadata changes.

Describe your contribution

In May support for Xamarin.Classic (monoandroid12) and net6.0 will be dropped and this is recon PR to see what is ahead of the team.

Build error:

    ./generated/androidx.emoji2.emoji2-emojipicker/androidx.emoji2.emoji2-emojipicker.csproj : error NU1605: 
      Warning As Error: Detected package downgrade: Xamarin.AndroidX.Emoji2 from 1.5.0.1 to 1.2.0.2. Reference the package directly from the project to select a different version. 
       Xamarin.AndroidX.Emoji2.EmojiPicker -> Xamarin.AndroidX.AppCompat -> Xamarin.AndroidX.Emoji2 (>= 1.5.0.1) 
       Xamarin.AndroidX.Emoji2.EmojiPicker -> Xamarin.AndroidX.Emoji2 (>= 1.2.0.2 && < 1.2.1)

In config.json

      {
        "groupId": "androidx.emoji2",
        "artifactId": "emoji2",
        "version": "1.2.0",
        "nugetVersion": "1.2.0.2",
        "nugetId": "Xamarin.AndroidX.Emoji2",
        "dependencyOnly": true
      },

changing it to fix the NuGet error to

      {
        "groupId": "androidx.emoji2",
        "artifactId": "emoji2",
        "version": "1.5.0",
        "nugetVersion": "1.5.0.1",
        "nugetId": "Xamarin.AndroidX.Emoji2",
        "dependencyOnly": true
      },

causes binderator error

Dependency errors : 1
1
	System.Exception: 
Artifact
	androidx.emoji2.emoji2-emojipicker:1.5.0
has unknown 'Runtime' dependency 
	androidx.emoji2.emoji2:[1.2.0]
Either fulfill or exclude this dependency.


An error occurred when executing task 'binderate'.
Error: .NET CLI: Process returned an error (exit code 1).

More investigation:

find ./generated -iname "*.csproj" -exec grep -Hni "1\.2\.0\.2" {} \;

./generated/androidx.emoji2.emoji2-emojipicker/androidx.emoji2.emoji2-emojipicker.csproj:112:    <PackageReference Include="Xamarin.AndroidX.Emoji2" Version="[1.2.0.2, 1.2.1)" PrivateAssets="none" />

Workaround (for now)

Exclude runtime dependency:

      {
        "groupId": "androidx.emoji2",
        "artifactId": "emoji2-emojipicker",
        "version": "1.5.0",
        "nugetVersion": "1.5.0.1",

        "excludedRuntimeDependencies": "androidx.emoji2:emoji2",
        "dependencyOnly": false
      },
