fix: Remove @internalapi from TableResult (#3257)

* fix: Remove @internalapi from TableResult

Since users depends on TableResult in testing, removing @internalapi forces maintainers to change/roll out changes to TableResult more carefully in the future.

* 🦉 Updates from OwlBot post-processor

See https://github.com/googleapis/repo-automation-bots/blob/main/packages/owl-bot/README.md

* Remove clirr ignore difference entries for TableResult
