Hid copy contents button on render error

Closes #218510

See merge request gitlab-org/gitlab!32632

When a blob returns a render error, we do not have the blob's content,
hence there's nothing to copy. That's why we hide the button in these
cases. However, if, for example, user forces loading the content (in
case of a collapsed blob), we do render the button again.

Add mutation to create a merge request in GraphQL

See merge request gitlab-org/gitlab!31867

- `Gitlab::CodeOwners::Validator` is an EE module
so anything depending on this needs to be in EE
- Inline `#codeowners_check_error`
- Use getter methods for instance vars in module

A new `reset_approval_rules_to_defaults` param that will be sent
by the frontend when approval rules are set to be reset to project
defaults.

When that param is set to `true`, the backend will delete all
existing any_approver/regular rules of the merge request. It will
also append inapplicable rules so it'll behave like creating rules
on MR creation.
