chore(coderd/database): add compile-time guard against import in slim build

mafredri · mafredri · commit 72655331a819 · 2023-09-04T17:10:18.000Z
This change introduces a compile-time error when `coderd/database` is imported into the slim build. This is to guard against accidentally growing the binary size via import. Ref: #9380
