config/output: Do not set adaptive_sync if not supported

After 4e38f93f36 ("config/output: Skip VRR tests when not supported"),
the configuration search no longer touches VRR state for outputs that
are known to not support it. This also means that it will not remove VRR
if already set, which could cause output configuration to fail.

Ensure that VRR state is never set for outputs that do not support it by
adding the same test for support to queue_output_config.
