Add Markdown output format to the CLI

[nineinchnick]

Description

Add Markdown output to avoid having to use external tools like csv2md.

Example usage:

./client/trino-cli/target/trino-cli-419-SNAPSHOT-executable.jar --output-format MARKDOWN \
  --execute="select * from (values (1234567, 'some longer strin'), (123, 'aa')) as t(one, two)"

Prints:

|     one | two               |
| -------:| ----------------- |
| 1234567 | some longer strin |
|     123 | aa                |

where the default ALIGNED format looks like:

   one   |        two        
---------+-------------------
 1234567 | some longer strin 
     123 | aa                
(2 rows)

I also tried using the CommonMark library, but its text renderer is lacking: master...nineinchnick:trino:cli-commonmark-output

I've tested rendering in various markdown editors and it looks good.

We've discussed offline to follow-up with the refactoring of the code coming from/being similiar to aligned writer. LGTM.
