Subject: [PATCH] build: Enable -Wcovered-switch-default

The leveldb exclusion is required to avoid this warning in the subtree:

```
src/leveldb/util/status.cc:63:7: warning: default label in switch which covers all enumeration values [-Wcovered-switch-default]
   63 |       default:
      |       ^
1 warning generated.
```
