Update `tuple.make` text format to include arity (#6169)

Previously, the number of tuple elements was inferred from the number of
s-expression children of the `tuple.make` expression, but that scheme would not
work in the new wat parser, where s-expressions are optional and cannot be
semantically meaningful.

Update the text format to take the number of tuple elements (i.e. the tuple
arity) as an immediate. This new format will be able to be implemented in the
new parser as follow-on work.
