Return the SQL schema for all DS queries in request (to provide information to AI / Autocomplete for SQL expressions).
All DS queries are treated as if they were inputs to SQL expressions in terms of conversion, regardless if they are selected in a query or not.
Requires feature toggle queryService = true
Endpoint is apis/query.grafana.app/v0alpha1/namespaces/default/sqlschemas

This is because MySQL doesn't support storing of NaN valuels, and therefore go-mysql-server isn't going to either.
Float fields/columns are always mapped to be nullable now, otherwise we would have to replace NaN/Inf with 0.
* SQL Expressions: Bump GMS for STDDEV(), VARIANCE()
Bump Go MySQL Server to the latest version, to get support for STDDEV()
and VARIANCE() functions, and their aliases.
See https://github.com/dolthub/go-mysql-server/pull/2928
* Update app-code to comply with latest GMS version
* Run `go mod tidy`
* Update test which had depended on STDDEV being missing
* Run `make update-workspace`
- use types.Convert to get a more normalized type returned from GMS. After syncing with GMS maintainers, the underlying type of the row could be different things (e.g. int when unit32, so this calls the Convert method from the GMS types library to normalize the interface.
- Clean up fieldValFromRow more
- Use IsText to capture different string types
- Add more types to test, also update test to use same cmp.Diff method as others
