  [clang-format] Don't allow casts in front of ampamp (#77704)

clang-format performs a heuristic to see if a right parenthesis is the
parenthesis of a cast expression. This check never looked ahead to see
if the next token is an ampamp && token. This resulted in the paren
being set as an CastRParen, and the following ampamp got annotated as an
UnaryOperator!

Since && can never be a unary operator is standard C++, this patch
forbids the right paren from ever becoming a cast.
