Add semantic coloring example from Android 17

[alabiaga]

• Add semantic coloring API sample in Live Update sample
• update Live Updates and app sample SDK level to 37 to make use of Semantic Coloring APIs
• modify agp as it's needed to support SDK level 37
• update build.gradle.kt files to support new agp 9.0+ changes

I'll follow up with another refactoring of the build gradle files as there are changes in agp 9.0 dsl that deprecates things and needs migration.

Code Review

This pull request updates the project to Android SDK 37, AGP 9.1.1, Kotlin 2.2.10, and Gradle 9.3.1. It migrates numerous sample modules to Java 11, refactors their build scripts to use a newer DSL structure by moving targetSdk to lint and testOptions blocks, and implements semantic style annotations for notifications. Feedback suggests removing the obsolete android.uniquePackageNames flag and correcting the android.newDsl setting, as it currently contradicts the DSL modernization efforts in the build files.
