72638: catalog/lease: avoid using context.Background directly r=ajwerner a=knz

First commit from #72651
Informs #58938.

- `(*AmbientContext).AnnotateCtx()` - takes care of connecting the
  context to the tracer
- `logtags.FromContext` / `logtags.WithTags` - reproduces the logging
  tags on the child context.

Release note: None

72640: sql/types: types.EnumMetadata implements encoding.TextMarshaler interface r=chengxiong-ruan a=chengxiong-ruan

Fixes #63379

`types.EnumMetadata` needs to implement `encoding.TextMarshaler`
interface so that goto/protobuf won't panic when text marshaling
protobuf struct has child field of type `types.EnumMetadata`.
See the issue for more details why it would fail without this
fix.

Release note: None

72650: streamingest: wait for all goroutines on streamIngestProcessor shutdown  r=andreimatei a=andreimatei

This processor was failing to stop and wait for some of the goroutines it
spawned, which is not nice (in particular, it's likely that those
goroutines were using a tracing span after it was finished).

Release note: None
