Stop conservatively rejecting none/normal/auto on newer <custom-ident…

…> values.

In w3c/csswg-drafts#7431 the CSS Working Group
resolved not to try to restrict none/normal/auto keywords, so there's no
need to reject them to avoid worsening potential compatibility problems.

Based on specs at https://drafts.csswg.org/css-contain-3/#container-name
and https://drafts.csswg.org/css-contain-3/#container-rule, this adjusts
ConsumeSingleContainerName to accept 'normal' and instead reject 'none'.
