Alerting: Persist annotations from multidimensional rules in batches (#56575)
* Reduce piecemeal state fields

* Read data directly off state instead of rule

* Unify state and context into single struct

* Expose contextual information to layer above setNextState

* Work in terms of ContextualState and call historian in batches

* Call annotations service in batches

* Export format state and reason and remove workaround in unrelated test package

* Add new method to annotation service for batch inserting

* Fix loop variable aliasing bug caught by linter, didn't change behavior

* Incl timerange on annotation tests

* Insert one at a time if tags are present

* Point to rule from ContextualState rather than copy fields

* Build annotations and copy data prior to starting goroutine

* Rename to StateTransition

* Use new bulk-insert utility

* Remove rule from StateTransition and pass in directly to historian

* Simplify annotations logic since we have only one rule

* Fix logs and context, nilcheck, simplify method name

* Regenerate mock
