LDAP: Restore test user mapping functionality (#110841)

* Migrate LdapPage from connect() to React-Redux hooks

* Convert LDAP debug page into a drawer and hook it into settings

* prettier

* Use the Text component and make the input and button look like they do on the main settings page.

* Bring back isLoading and put in a LoadingPlaceholder

* i18n-extract

* rejigger

* linter fix
