In #934, we changed command calls to return nil only. This PR improves
the behaviour even further by:
- Not echoing the `nil` returned by command calls
- Not overriding previous return value stored in `_` with the
`nil` from commands

* Make help command display help for individual commands
Usage: `help [command]`
If the command is not specified, it will display a list of all available commands.
If the command is specified, it will display the banner OR description of the command.
If the command is not found, it will display a message saying that the command is not found.
* Rename test/irb/cmd to test/irb/command
* Add banner to edit and ls commands
* Promote help command in the help message
1. Make `show_cmds` an alias of `help` so it's not displayed in the help message
2. Update description of the help command to reflect `help <command>` syntax
* Rename banner to help_message

* Test IRB's behaviour with empty input
* Handle empty input and pass it to debugger
Since `rdbg` accepts empty input to repeat the previous command, IRB
should take empty input in `irb:rdbg` sessions and pass them to the
debugger.
Currently, IRB simply ignores empty input and does nothing. This commit
creates `EmptyInput` to represent empty input so it can fit into the
current IRB's input processing flow in `Irb#eval_input`.
