refactor: split instance module into vm/ and machine/ sub-packages

The pkg/providers/instance/ package contained both VM-based and
AKS Machine-based provider implementations in a flat structure,
with only filename prefixes distinguishing them. This made it harder
to reason about ownership and prevented natural Go package boundaries.

Split into:
- instance/vm/: VMProvider, ARM utils, ARG queries, VM metrics
- instance/machine/: AKSMachineProvider, template helpers, utils
- instance/machine/poller/: renamed from aksmachinepoller/
- instance/ (parent): Promise interface (shared by both)

The two provider paths share no concrete types — the only shared
abstraction is the Promise interface. This split makes the separation
explicit and enables cleaner dependency management.

Also applies to the azclient God-object and ARG code placement,
which are noted as follow-up improvements.
