SSE/NG: Add expression metadata for EvalMatch (#32213)
- Add the ability to stick metadata attached to a value in expressions. Currently uses Frame.Meta.Custom.
- None of this is consumed by anything yet, so an incremental step.

SSE/Alerting: First pass at query/condition translation (#31693)
- Takes the conditions property from the settings column of an alert from alerts table and turns into an ng alerting condition with the queries and classic condition.
- Has temp API rest endpoint that will take the dashboard conditions json, translate it to SEE queries + classic condition, and execute it (only enabled in dev mode).
- Changes expressions to catch query responses with a non-nil error property
- Adds two new states for an NG instance result (NoData, Error) and updates evaluation to match those states
- Changes the AsDataFrame (for frontend) from Bool to string to represent additional states
- Fix bug in condition model to accept first Operator as empty string.
- In ngalert, adds GetQueryDataRequest, which was part of execute and is still called from there. But this allows me to get the Expression request from a condition to make the "pipeline" can be built.
- Update AsDataFrame for evalresult to be row based so it displays a little better for now

SSE: Add "Classic Condition" on backend (#31511)
This is a translation of services/alerting/conditions. Main Changes:

- Work with types in SSE (series/number) which are data frames (no more null.Float).
- The query part from alerting/conditions is handled by SSE logic
- Convey / simplejson removed.
- Time range no longer part of "query" in the condition
