Allow overriding of project approvers in merge request

See merge request gitlab-org/gitlab!34026

Previously specifying blank `user_ids` and `group_ids` during the
creation of a merge request approver rule would cause the merge request
to inherit from the project rule. However, that prevents users from
setting the merge request approvers to "any approver". To fix this, we
only set the "any approver" type if `user_ids` and `group_ids` is not
specified and no project approvers are present.

In addition, this commit also fixes the approval rule type when project
rule has users/groups.

Suppose a project has an approval rule that includes specific users or
groups as approvers. If a user attempts to create a merge request
approval rule based on this project rule but omits `user_ids` and
`group_ids`, previously this rule would be erroneously assigned "any
approver". However, the project approvers should be inherited.

To fix this, we:

1. First copy the project approval rules.

2. If the newly-modified params indicate specific users or groups, don't
assign the merge request rule the "any approver" type.
