Added a sqlXPassThrough layer (#18238)

* Added a sqlXPassThrough layer

This layer embeds the original sqlx object and wraps some
key methods to avoid some boilerplate.

- Add timeout to all methods from the timeout in settings.
- Added trace functionality.
- Added auto-rebind capabilities so that each store method
doesn't need to call rebind every time.
- Added auto-lowering of query string to support NamedExec
for both MySQL and Postgres

All methods are not wrapped as all are likely not to be called
from our code. As and when they are called, support will be added.
