Switch to upstream SQLite driver

[jlegrone]

What changed?

This PR removes SQLite driver code that has been recently moved to temporalio/temporal.

Why?

The upstream driver code is now being tested alongside each change to the Temporal server codebase, which will help ensure stability and compatibility across version upgrades.

How did you test it?

Automated tests in CI

Potential risks

This change removes support for non-cgo builds, and there's no guarantee that this will be added back upstream.

Is hotfix candidate?

No
