[EuiText] Add kbd styles (#6049)

* [EuiText] Adding `kbd` styles

* Adding CL

* Better comments and styles

* [PR feedback] Minor cleanup

- Remove extra newlines
- Remove extra semicolons (already added by logicalCSS() util)
- Refactor 1px border width to `thin` var
- Refactor conditional kdb logic to `euiScaleText` vs a new util
