Fix aar artifacts publication for Maven

[romtsn]

📜 Description

Gradle has a bug gradle/gradle#3170, where they don't assign the aar artifact type to android libraries, so Maven (the build system) cannot automatically infer the correct type, hence our artifacts cannot even be downloaded, when using Maven instead of Gradle.

We're just working it around by modifying the pom.xml file.

The workaround is slightly adapted from https://github.com/androidx/androidx/blob/c799cba927a71f01ea6b421a8f83c181682633fb/buildSrc/private/src/main/kotlin/androidx/build/MavenUploadHelper.kt#L524-L549

💡 Motivation and Context

Closes #1947

💚 How did you test it?

Manually published to maven local
