EE: Reorganize indexes for the "deployments" table

Closes gitlab-ce#36877

See merge request gitlab-org/gitlab-ee!2955

Do not perform hard check (presence of file on storage)

Closes gitlab-ce#37945

See merge request gitlab-org/gitlab-ee!2960

This removes the need for a default scope that adds a "WHERE project_id
= X" clause. This commit also includes an additional index for
Environment#last_deployment, ensuring this query uses just an index scan
instead of also applying a Filter.

Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/36877
