Investigate pinning Android SDK components inside CI #59778
Description
We already had at least two different CI issues caused by the Android SDK's sdkmanager:
- Fix Android CI failing to download SDKs #57857: a new license was added and sdkmanager failed to accept it with the old command
- arm-android docker image is broken after a rebuild #59757: the emulator was updated to a broken (at least for us) version, causing all builds to fail
The root cause of those issues is that sdkmanager doesn't support any kind of pinning (as far as I can tell), and any change Google makes can break our CI.
Should we develop a pinning mechanism and use it for all the Android SDK components?
