gitlab_*_variable: support masked-and-hidden variables (#10787)

* gitlab_*_variable: support masked-and-hidden variables

Support masking and hiding GitLab project and group variables. In the
GitLab API, variables that are hidden are also masked by implication.
Note gitlab_instance_variable is unmodified since instance variables
cannot be hidden.

* gitlab_*_variable: add `hidden` to legacy `vars` syntax

* gitlab_*_variable: address review comments in doc
