ci: use fresh AVD from benchmark tests

[CAMOBAP]

Caching AVD for Android is a questionable practice due to the complexity of emulator setup and unwanted states that should not be stored between CI runs. As a result, this leads to unstable tests on CI.

We definitely should avoid it for benchmarking, as the environment must be as clean as possible between runs.
