Set reconcile-policy: skip on ASO resources when Cluster is paused

[nojnhuh]

Since a Cluster's spec.paused indicates whether reconciliation is disallowed, CAPZ should communicate that intent with ASO so all reconciliation stops when spec.paused is true. Likewise, when a Cluster is unpaused, reset the reconcile-policy annotation to its previous value (reconcile-policy may have already been skip even before the Cluster was paused if the corresponding Azure resource is managed by the user).

Note: Since annotating all ASO resources is not an instantaneous operation, CAPZ may be able to perform a best-effort "pause reconciliation of as many ASO resources as possible" even without the above dependency, but it might turn into a bit of a minefield for flakes in tests involving clusterctl move.

This is the strategy for now as a result of the tests done in #3795. #3839 will fill the gap down the road. Otherwise the work for this issue is complete.
