add support for company-kind

[jidibinlin]

If we add company-kind support. completion front end such as corfu can get the kind information to implement more feature. For my purposes I can use it to make corfu support icon display when pop up the completion frame.

Looks good in principle, but please remove unrelated whitespace changes first.

[jidibinlin]

Alright, But I suggest you automatically delete whitespace when you save buffer. I will remove unrelated whitespace changes.

@joaotavora This pr can be merged?

[joaotavora]

No it needs better commit messages and better formatting. I don't have time right now so be patient. The idea is good. Maybe you can guess from other commits the coding standards
