If we don't handle Lazy types specifically in `renderDebugModel`, all of
their properties will be emitted using `renderDebugModel` as well. This
also includes its `_debugInfo` property, if the Lazy comes from the
Flight client. That array might contain objects that are deduped, and
resolving those references in the client can cause runtime errors, e.g.:
```
TypeError: Cannot read properties of undefined (reading '$$typeof')
```
This happened specifically when an "RSC stream" debug info entry, coming
from the Flight client through IO tracking, was emitted and its
`debugTask` property was deduped, which couldn't be resolved in the
client.
To avoid actually initializing a lazy causing a side-effect, we make
some assumptions about the structure of its payload, and only emit
resolved or rejected values, otherwise we emit a halted chunk.
