Support disabled state in gl-dropdown-item

The current gl-dropdown-item doesn't seem to support a disabled state > https://gitlab-org.gitlab.io/gitlab-ui/?path=/docs/base-dropdown-dropdown-item--default.

However, in Bootstrap, this is supported > https://getbootstrap.com/docs/4.0/components/dropdowns/#disabled-menu-items

Can we explore into adding support of this?
