Get rid of using legacydata.RequestHandler in HTTPServer, /api/tsdb/query and pkg/expr
with the goal of deprecating /api/tsdb/query and remove it completely eventually. This is
the first step of cleaning up the HTTP API query endpoint.

Refactor usage of legacy data contracts. Moves legacy data contracts
to pkg/tsdb/legacydata package.
Refactor pkg/expr to be a proper service/dependency that can be provided
to wire to remove some unneeded dependencies to SSE in ngalert and other places.
Refactor pkg/expr to not use the legacydata,RequestHandler and use
backend.QueryDataHandler instead.
Fix bug with engine cache not updating after data source updated, introduced in #36635.
Removes the SQL engine cache because since #36635 we already have instance caching in place using the SDK instance manager.
This also adds support for disposing cached SQL/xorm engines before a query happens to a data source that has been updated. Done by letting the SQL engine implementing the InstanceDisposer interface.
Fixes#37299
Adds a new setting dataproxy.row_limit that allows an operator to limit the
amount of rows being processed/accepted in response to database queries
originating from SQL data sources.
