Add GitLab-wide predefined status messages

Problem to solve

With https://gitlab.com/gitlab-org/gitlab-ce/issues/35463 we are adding the option to add a status message (emoji and text) to your user profile. In this first iteration, the status information can be added from the user profile preferences.
A short list of predefined statuses for common use cases/reference is missing.

Proposal

Let's work out a few predefined status messages that cover relevant GitLab use cases and add them as an alternative to a custom message. Pre-defined status messages consist of an emoji and a message. These will be shipped as built-in. options.
Proposals to discuss.

Emoji Message
🏡 Working remotely
🤒 Out sick
🌴 Vacationing
📪 Out of office
💤 Away
more ?

What does success look like, and how can we measure that?

A list of predefined status messages are available in addition to adding custom statuses.
