Chris Williams fe0191c62c [CSSimplify] Parameter pack wrapping logic incorrectly considers tuple LValueTypes to not be tuples (#85962) ...

In #65125 (and beyond) `matchTypes`, has logic to attempt to wrap an
incoming parameter in a tuple under certain conditions that might help
with type expansion.

In the case the incoming type was backed by a `var`, it would be wrapped
by an `LValueType` then be subsequently mis-diagnosed as not-a-tuple.

More details in #85924 , this this is also the cause of (and fix for)
#85837 as well...
