feat(enterprise): implement organization "disable workspace sharing" option (#21376)

Adds a per-organization setting to disable workspace sharing. When enabled,
all existing workspace ACLs in the organization are cleared and the workspace
ACL mutation API endpoints return `403 Forbidden`.

This complements the existing site-wide `--disable-workspace-sharing` flag by
providing more granular control at the organization level.

Closes https://github.com/coder/internal/issues/1073 (part 2)
