gccrs: Break OR tokens in closure parameter list context
The parser was unable to process as closure inside a closure because the
lexer could not differentiate an OR from two PIPE tokens.
gcc/rust/ChangeLog:
* parse/rust-parse-impl.h (Parser::parse_closure_expr_pratt): Fix
closure parsing function to handle consecutive parameter lists.
