Upgrade rust/crates/tokio to 1.6.0 and use cargo2android.json to generate bp file

1. Only generate libtokio by cargo2android.json
2. Put all the test targets to patch, which might let future upgrade
   easier.
3. Add some tests removed by previous upgrade back.
4. Disable some tests that doesn't work for Android.

Test: atest
