Currently, --async-executor option to switch the backend of cros_async::Executor is a global option of crosvm main command. This is because --async-executor is an option to switch the async runtime backend engine of cros_async crate for a whole crosvm. However, in practice, only run, device, and devices subcommands have the motivation to switch the backends for the performance. Other subcommands may or may not use async functions, but it's unlikely they want to switch the backends. So, it makes sense to make --async-executor an option of those three subcommands, not of the global option. Also, it allows us to switch --async-executor in arvm_dev.conf, which overrides the options for `crosvm run` command, and to control the async executor by the coming configuration file feature. Thus, this commit moves the --async-executor option from the global command to the run, device, and devices subcommands. This is a breaking change, but it is unlikely to have many users using this relatively new option. Takayas also confirmed there's no usage on codesearch.

crosvm - The Chrome OS Virtual Machine Monitor
crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.
crosvm is currently used to run Linux/Android guests on Chrome OS devices.
