[vm] Enable new implementation of async/await in AOT mode

The new implementation results in a much smaller overhead of
async/await on AOT snapshot size. The savings depend on
how often async/await is used.

On a large Flutter app (customer: money)
AOT snapshot size -13.7% (arm64), -12.86% (arm)

Another large Flutter app
AOT snapshot size -8.69% (arm64).
