Extend DUMP & RESTORE commands to support Garnet objects

### Feature request type

enhancement

### Is your feature request related to a problem? Please describe

The [`DUMP`](https://redis.io/docs/latest/commands/dump/) command serializes a value at a specified key and dumps the serialized value to the client. The serialized value can then be deserialized and stored using the [`RESTORE`](https://redis.io/docs/latest/commands/restore/) command.

Currently, Garnet supports the DUMP & RESTORE commands for string values only. We're looking for help implementing this command for all other supported object types (Set, SortedSet, HashSet, List).

### Describe the solution you'd like

Extend implementation of `DUMP` and `RESTORE` command in Garnet to support objects.

**References:**
Serialization format [specification](https://rdb.fnordig.de/file_format.html).
Existing `DUMP` and `RESTORE` code in [KeyAdminCommands.cs](https://github.com/microsoft/garnet/blob/main/libs/server/Resp/KeyAdminCommands.cs) (see: `NetworkDUMP` and `NetworkRESTORE`)

### Describe alternatives you've considered

### Additional context

_No response_

Start in libs/server/Resp/KeyAdminCommands.cs with NetworkDUMP and NetworkRESTORE, then compare the referenced serialization format specification with the existing string support. Extend the commands for Set, SortedSet, HashSet, and List objects, and verify that each supported object can be dumped and restored using the specified format.
