kunit: tool: drop last uses of collections.namedtuple Since we formally require python3.7+ since commit df4b0807ca1a ("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.

kunit: tool: Add support for overriding the QEMU serial port 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.
