Format library: add Keyboard Input (<kbd>)

[ellatrix]

Description

Fixes #17879.

But that is by far not enough. The intention of this ticket (more like feature request than a bug report) -- support for <kbd> tags -- was to have any kind of support for <kbd> tags in Gutenberg, i.e. any ability to add this tag to Visual Editor without the need to switch to Code Editor each time you need to add <kbd> tag.

A new button will be added in the overflow rich text menu.

As well as I can test, pasting the tags also works. For example, paste the this paragraph with this test.

If there's any remaining issues with <kbd>, please open a new issue.

How has this been tested?
