Ferrochrome: Re-enable tests with more safe guards
This CL includes following changes
- Ensure whether adb root success
- Find and launch VM launcher based on intent action
- Ensure that both host and DUT have enough space
- Ensure arm64 arch
- Ensure non-virtual device
- Remove pushed image when test is finished (kill vmlauncher for it)
- Enable verbose log by 'set -x'
