Allow specifying attributes for RequestMatcher

[mdoutreluingne]

fixes #17377

Could you help me with the XML and PHP formats.

• Add YAML example format
• Add XML example format
• Add PHP example format

Thank you!

The other formats would look like this:

<rule role="ROLE_ADMIN">
    <attribute key="_route">admin</attribute>
</rule>

<rule route="admin" role="ROLE_ADMIN"/>

(btw, you were actually right - XML was not yet supported for this setting, I've contributed a fix: symfony/symfony#47959 )

$security->accessControl()
    ->roles(['ROLE_ADMIN'])
    ->attributes(['_route' => 'admin'])
;

$security->accessControl()
    ->roles(['ROLE_ADMIN'])
    ->route('admin')
;

What does WCM in the title means?

WCM means 'Waiting Code Merge', Wouter has created a PR to add the XML format
