Hostagent should have separate binary (at least on Windows hosts)

[arixmkii]

Description

On Windows hosts host agent should be linked as a GUI application for correct background processing, but limactl should still be console application.

Example of this could be found here.

Example of the actual issue. If Ctrl-C is sent to the terminal, where limactl was launched, which in order started limactl host agent, it will kill the host agent. Or if you close the console window it will also terminate the HA, which is not expected behavior.
