token-cli: Add check withdraw-withheld-tokens has sources or include mint

[zzau13]

Just check both conditions and return error. Clap doesn't have the method for check that, so I do check in command logic.
Fixes #7042

I pointed out how to do this with clap using an ArgGroup, could you switch it to that? We can do:

                .group(
                    ArgGroup::with_name("source_or_mint")
                        .arg("source")
                        .arg("include_mint")
                        .multiple(true)
                        .required(true)
                )

This gives a nice error message:

$ spl-token withdraw-withheld-tokens AqANLp9HPtk9Lc1qpMSH9ijqMxMXKvFCEdg8M3P3Mi6X
error: The following required arguments were not provided:
    <source|--include-mint>

USAGE:
    spl-token withdraw-withheld-tokens [FLAGS] [OPTIONS] <TOKEN_ACCOUNT_ADDRESS> <source|--include-mint> [--]
