c++: Fix ICE in tsubst_copy with parenthesized expression [PR93299]
Since e4511ca2e9ecdb51d41b64452398f8e2df575668 force_paren_expr can create
a VIEW_CONVERT_EXPR so that we have something to set REF_PARENTHESIZED_P
on, while not making the expression dependent. But tsubst_copy can't cope
with such a VIEW_CONVERT_EXPR, because it's not location_wrapper_p, or
a TEMPLATE_PARM_INDEX wrapped in a VIEW_CONVERT_EXPR.
I think we need to teach tsubst_copy how to handle it. Setting
EXPR_LOCATION_WRAPPER_P in force_paren_expr would make the ICE go away
too, but tsubst_copy would lose the REF_PARENTHESIZED_P flag.
