deprecate separate review options #375

In #358, the PR reviews' suggestions/patch has advice merged both tools. It no longer makes sense to have separate input options for each tool.

Proposal

Replace --tidy-review and --format-review with --pr-review. I think I can make --tidy-review and --format-review aliases for --pr-review for backward compatibility.

Filtering tools' advice

Users can still set --ignore-format and --ignore-tidy to prevent advice about certain files from certain clang tools.
