There are still rough spots for sure, specifically around the podman socket and pipe. This implemention is only for Linux. All other providers are still present but will not compile or work. This is why tests for them have been temporarily suspended. The ready socket code is another area that needs to be smoothed over. Right now, the ready socket code is still in QEMU. Preferably it would be moved to a generic spot where all three approaches to readiness socket use can be defined. It should also be noted: * all machine related tests pass. * make validate for Linux passes * Apple QEMU was largely removed * More code pruning is possible; will become clearer when other providers are complete. the dir pkg/machine/p5 is not permanent. i had to seperate this from machine initially due to circular import problems. i think when all providers are done (or nearly done), it can be placed and named properly.

refactor used specifically qemu for testing and infra bring up. But the whole point was to have things interfaced. This PR results in an interface experience like podman 4 using the same term `provider` to generically represent 'a provider' like qemu/applehv/etc. This PR is required to move forward with new providers. Also renamed pkg/machine/p5 to pkg/machine/shim.

Abstracts the functionality out to a method of `MachineConfig`. WSL currently uses a function `SetRootful` that is provided by the `machine` package, which will eventually get changed when WSL moves to the refactored structure. Re-enables the "set rootful with docker sock change" test.
