[Cherry-pick] Support AGP 9 and improve compatibility handling for AGP < 8.10 (#5473)

Support AGP 9.0.0-alpha01 and improve compatibility handling for AGP <
8.10

- Updated Gradle to support version 9.0.0.
- Improved Compose resource configuration to handle AGP versions below
8.10 with a fallback implementation.
- Bumped Kotlin to 2.2.0 release and updated related dependencies.
- Adjusted tests to reflect changes in AGP-specific behavior and
logging.

Fixes https://youtrack.jetbrains.com/issue/CMP-8771


(cherry picked from commit f68b30d)
