On some platforms, the console is not the first serial port. To make
this work, the first serial port in QEMU must be set to "null".
Add support for this by adding an optional "serial" parameter, which
defaults to "stdio", and can be overridden by platform-specific
configuration.

Since we formally require python3.7+ since commit df4b0807ca
("kunit: tool: Assert the version requirement"), we can just use
@dataclasses.dataclass instead.
In kunit_config.py, we used namedtuple to create a hashable type that
had `name` and `value` fields and had to subclass it to define a custom
`__str__()`.
@datalcass lets us just define one type instead.
In qemu_config.py, we use namedtuple to allow modules to define various
parameters. Using @dataclass, we can add type-annotations for all these
fields, making our code more typesafe and making it easier for users to
figure out how to define new configs.
