This allows us to get rid of some of the validation in sanity_checks()
as mypy handles this validation at "build time", and any typos in the
enum instantiation would be a runtime error rather than a silent
failure.
Additionally, it allows us to encode some of the behaviour of the
different output types into the type definition itself by using methods.

Cease merging pmbootstrap.cfg into args, implement a Context type to let
us pull globals out of thin air (as an intermediate workaround) and rip
args out of a lot of the codebase.
This is just a first pass, after this we can split all the state that
leaked over into Context into types with narrower scopes (like a
BuildContext(), etc).

The current mechanism of invoking pmbootstrap actions can be a bit
confusing, and relies heavily on args being a big namespace with lots of
properties (which may or may not be valid depending on the context).
To aid in slowly removing args from the codebase, introduce a new
mechanism for running commands. This works by having a class for each
command, where the arguments are passed in as parameters to the
constructor.
No doubt this won't scale very far, but it's a skeleton we can continue
to build on as we migrate more commands over to not require args in
order to run.
