Add AppendWithVerify and PositionedAppendWithVerify to Env and FileSy…

…stem (#7419)

Summary:
Add new AppendWithVerify and PositionedAppendWithVerify APIs to Env and FileSystem to bring the data verification information (data checksum information) from upper layer (e.g., WritableFileWriter) to the storage layer. This PR only include the API definition, no functional codes are added to unblock other developers which depend on these APIs.
