Add GetFileHandle method to dump entry

This commit introduces the GetFileHandle method in the dump entry
interface. This method provides direct access to the Unix file
handle of the dump entry, facilitating more direct read operations
on the dump file.

The returned file descriptor will be read-only, ensuring the integrity
of the dump file.

This change is primarily introduced to support the PLDM for offloading
the dump to the host and bmcweb for offloading the dump to Redfish
clients. Previously, a direct file path was provided for these
operations. However, if the applications are running in a non-root
context, they may lack the necessary access to the file. By providing
a file handle, this access issue is resolved.
