When computing the code size estimate for {PrepareAndStartCompile}, we
did not consider Liftoff code in the async path. Other invocations
checked {FLAG_liftoff} to decide whether Liftoff code will be generated.
This CL fixes the async path to do the same, and renames {uses_liftoff}
to {include_liftoff} to match the name of the parameter in
{EstimateNativeModuleCodeSize}.
