Subject: [PATCH] [Project][Codeformat] Added prettier as partial formatter for
 JS

[Feature] Existing solution check the format using eslint and fix
some issues with predefined rules (which match the requirements
of review.tizen.org CodingRule_Auto bot rules.
However the tool checks the validity, it does not provide auto
formating of too long lines issues.
To ensure such feature, the new tool was introduced and executed before
eslint validation.
Thanks to prettier, the line breaks are unified and handled the same
way in whole project.
