soroban-cli: replace lab xdr subcommand with embedding the stellar-xdr cli

[leighmcculloch]

The soroban-cli has a lab xdr sub command that supports decoding XDR.

However, the stellar-xdr cli tool has more features and is likely to be developed further than the soroban-cli's xdr command.

We should embed the stellar-xdr cli inside the soroban-cli, so that the soroban-cli benefits from the stellar-xdr.

Tasks

Just to clarify, the scope of this issue is to essentially merge stellar/rs-stellar-xdr into soroban-cli, right? Should we deprecate/remove the original repo in that case?

No, the scope of the issue to embed the tool.
