Add has_shimo to project_settings table

Reference MR: !35485 (merged)

Blocked MR: !74140 (merged)

What does this MR do?

This change adds a new boolean column to project_settings to allow caching the status of the new Shimo integration as has_shimo.

The new has_shimo property is unable to be added to projects, like the other has_{x} columns, as we are not allowed to migrate new columns to projects due to its width.
