Summary:
### Embedded Blob Resolving Iterator Fix
#### Use-After-Free Bug Fix
This diff fixes a use-after-free bug in the `EmbeddedBlobResolvingIterator` class. The bug occurred when the `key()` method was called before the `value()` method, causing the `resolved_internal_key_` buffer to be freed prematurely.
#### Changes
The fix involves modifying the `EmbeddedBlobResolvingIterator` class to ensure that the `resolved_key` is not moved into `resolved_internal_key_` if it has already been resolved (`key_resolved_` flag is set to `true`). This prevents the `resolved_internal_key_` buffer from being overwritten and freed when `MaterializeValue()` is called.
