Hide "Availability" and "Calendar" on user profiles for disabled users

Summary:
See downstream <https://phabricator.wikimedia.org/T138723>. That suggestion is a little light on details, but I basically agree that showing "Availability: Available" on disabled user profiles is kind of questionable/misleading.

Just hide event information on disabled profiles, since this doesn't seem worth building a special "Availability: Who Knows, They Are Disabled, Good Luck" disabled state for.

Test Plan: Looked at…
