Add Serialization Support for Dump Entry Attributes

Implemented serialization of dump entry attributes using the
nlohmann::json library. Added serialization support in the Dump Entry
class, serializing attributes including originatorId, originatorType,
and startTime. These attributes are not part of the dump filename and
thus require serialization to ensure their state is preserved.

Deserialization will occur only if the serialization version matches
and the dump ID in the dump object matches the ID in the
serialized file.

Tests:
- Created BMC dumps and restarted service
- Created BMC dumps and restarted BMC
- Created 200 BMC dumps and restarted service and BMC multiple times

File:
```
{"dumpId":2,"originatorId":"","originatorType":1,"startTime":1718199238942411,"version":1}

Implement GetFileHandle in dump entry interface

Certain applications need to offload the dump in various
ways, for example, performing DMA transfer of the dump to
the host memory. These applications require direct access
to the file to read from the BMC storage.

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 is read-only, which ensures
the integrity of the dump file.

The definition of the file handle is moved from the
specific 'bmc_dump_entry' class to the parent 'dump_entry'
class. This allows all dump types inheriting from
'dump_entry' to use this new method, thus increasing
its utility across various dump types.

The introduction of this method primarily benefits PLDM
for offloading the dump to the host, and bmcweb for
offloading the dump to Redfish clients. By providing
a file handle instead of exposing the file path,
it resolves potential access issues for applications
running in non-root contexts.

Test:
Created a dump and made sure it reached host
successfully
