Context:
1. all_tests_uml.config used to be UML specific back when users to
manually specify CONFIG_VIRTIO_UML=y to enable CONFIG_PCI=y.
2. --alltests used allyesconfig along with a curated list of options to
disable. It's only ever worked for brief periods of time and has
perennially been broken due to compile issues.
Now all_tests_uml.config should work across ~all architectures.
Let's instead use this to implement --alltests.
Note: if anyone was using all_tests_uml.config, this change breaks them.
I think that's unlikely since it was added in 5.19 and was a lot to
type: --kunitconfig=tools/testing/kunit/configs/all_tests_uml.config.
We could make it a symlink to the new name, but I don't think the
caution is warranted here.
