DAP: introduce Rdbg Trace Inspector

[ono-max]

We'll introduce a new feature Rdbg Trace Inspector. This is useful when tracing in VS Code.

How to use it

1. Click on "Start Trace" in TRACE view
2. Execute the program

That's it! You can check the location and returned value by clicking the trace log.

How to choose events

On the default, line, call, and return events are selected.

If you want to change the default, click "more items", then choose events in the context menu.

I've been wanting this feature for a while, this looks super cool 🎉
Quick question: how can we select the even type with this UI (e.g. exclude the line events)? From the video I don't see an option to do so. It'd be helpful to skip some events in large codebases. And it'd be great if we can include raise events too.
Also, is it possible to have some protocol tests for it?

We can select the option as follows:

Yeah, I think that we can add tests.

LENGTH -> RECORDS

or LOGS if you u se @log

# Now it is only for DAP

cut off to the method

else
raise "unknown trace type #{evt}"

Another idea:

EVENTS = {'line' => [:line], ...}

def ...
  evts = []
  events.each{|evt| evts.concat EVENTS[evt]}
  ...

or

  evts = events.flat_map{|evt| EVENTS[evt]}

But the current code makes sense because it is easy to read.

other subcommands are verbs so I recommend to use collect (a verb word)

Yeah, I think that we can add tests.

@ono-max Thanks. Could we first have some tests in the same PR?

[ono-max]

I'll try it, but I'm not sure if I can add tests in the same PR because I'm busy right now. There is a possibility they are added in the other PR. Sorry.
