VACMS-3323: Upgrade simplesamlphp library and Drupal module (#3336)

* Remove old patch "Bypass password requirement for password change if logged in with sso".

* Apply new patch for "Don't attempt username sync when user was already matched by username".

* composer require simplesamlphp/simplesamlphp:^1.18 drupal/simplesamlphp_auth

* Set login_link_show for module, disabled by default.

Fixes failure:

And I should see "Login with PIV or other Smartcard." in the
"#edit-simplesamlphp-auth-login-link" element #
Drupal\DrupalExtension\Context\MinkContext::assertElementContainsText
during behat test run for the user.feature.

* Update top-level, non-vendor simplesamlphp-1.17.2 to 1.18.8.

* Add default config templates to /config/.

* Add custom /config/{authsources,config}.php back.

Skipped the below as they are not options in the new config and I don't
think we need them:

    'default-wsfed-idp' => 'urn:federation:pingfederate:localhost',
    'enable.wsfed-sp' => false,
    'enable.authmemcookie' => false,

* Add default /metadata/saml20-idp-remote.php template.

Left the others out because I don't think they are used.

* Add custom config to /metadata/saml20-idp-remote.php.

* Use a symlink for simplesamlphp instead of copy whole folder.

* Add symlink, remove duplicate IDP, remove unneeded files.

* composer require simplesamlphp/simplesamlphp:^1.18 drupal/simplesamlphp_auth
