Fix cpp_peek_token behaviour (PR bootstrap/50778)
libcpp/
* include/internal.h (_cpp_remaining_tokens_num_in_context): Take the
context to act upon.
* lex.c (_cpp_remaining_tokens_num_in_context): Likewise. Update
comment.
(cpp_token_from_context_at): Likewise.
(cpp_peek_token): Use the context to peek tokens from.
