Treat '!' as EOF in in ConsumeGridTemplateRowsAndAreasAndColumns
Our property parser should generally stop at first unknown token
to allow the caller to handle any trailing !important.
CL:5509594 (and/or related CLs) did however introduce a few exceptions
to this for practical purposes. These exceptions need to handle
the sudden appearance of '!' following an otherwise valid value,
but we forgot do that in one of the branches in ConsumeGridTemplate-
RowsAndAreasAndColumns.
