Revert "android: Roll latest releases of emulator and system image for AVD creation"

This reverts commit 4019e30a.

Reason for revert: Need to create new AVDs for crrev.com/c/2146136 and crrev.com/c/2321088. Revert this CL to avoid affect from emulator/system image change.

Original change's description:
> android: Roll latest releases of emulator and system image for AVD creation
> 
> API 23:
>   emulator version: 29.0.11 -> 30.0.12
>   system image: 31 -> 32
> API 28:

>   system image: 9 -> 10
> API 28 with playstore:
>   emulator version: 30.0.0 -> 30.0.12
