chore: scripts: allow starting the Android emulator locally on Linux

[istankovic]

Use the canonical avdmanager location to store AVDs. Shut down the emulator instance if it is running. Don't delete and recreate the AVD every time, only create an AVD if there isn't one already.

Direct emulator logs to a temporary file and tell the user about it so they can debug possible issues with the emulator instance. Don't needlessly list all packages, prolonging the script run time.

Also, rename the script to better reflect what it does.
