Add Android SDK setup and emulator dependencies for metal runner

The custom metal runner lacks pre-installed Android SDK and X11
libraries that GitHub-hosted runners have. This adds:
- dnf packages for X11/graphics libs required by the emulator
- android-actions/setup-android@v3 to install and configure the SDK
- sdkmanager step to install emulator, platform-tools, and system image

Fixes "undefined/platform-tools/adb" path issue and "Could not open
libX11-xcb.so.1" error.
