[CI:MACHINE]Podman5 QEMU refactor 

The following PR is the leading PR for refactoring podman machine with
the following goals:

* less duplication/more re-use
* common configuration file between providers
* more consistentency in how machines are handled by providers

The goal of this PR is the rough refactor.  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.
