Add default constructor to Ort::Status. (#25860)
### Description
<!-- Describe your changes. -->
Fix packaging pipelines
### Motivation and Context
<!-- - Why is this change required? What problem does it solve?
- If it fixes an open issue, please link to the issue here. -->
During CIs and local builds Ort::Status() gets inherited from the base
due to using directives,
however, that does not work for packaging pipelines.
Having default ctor is important for storing Status in containers if
needed.
