[css-gaps-1] Duplicate definition of repeat()

[tidoust]

CSS Gaps defines a repeat() function already defined in CSS Grid Layout. Both definitions are global, so that creates a duplicate, see for example the cross-referencing database.

Is the definition in CSS Gaps meant to supersede the one in CSS Grid Layout?
If not, it needs to be namespaced somehow.

I think it would make sense to namespace both definitions: the one from CSS Grid for="<track-repeat>,<auto-repeat>,<fixed-repeat>,<name-repeat>" and the one from CSS Gap for="<repeat-line-color>,<auto-repeat-line-color>".

Thanks for pointing this out. Created #11388 to namespace in both specs.
