AOSP 10 Support for lunch sdk_phone64_arm64

[Tanuj Bhatia]

Hello , 

I am trying to build an  emulator for android 10 for MAC sillicon chip devices . 

For Reference  tried downloading ARM image available on AVD manager by default works on Mac sillicon . But upon checking the Build meta data , could find the lunch command for that system-image i.e sdk_phone64_arm64. 

But i am not able to locate same on any of the android 10 branches . Instead there was sdk_phone_arm64 only which never boots up on android  

PLease help share the correct branch for above lunch command  to work

Thanks
