  "message": "Add `{,Dynamic,Unbound}FieldSkipper()`.\n\nIt becomes increasingly common to do nothing in a field handler besides tracking\nfield presence. It is annoying to write lambdas which takes the value, context\nparameters, and just returns `absl::OkStatus()`, and it feels uncertain whether\ntaking and ignoring the value is as efficient as it could (it almost is;\narranging for this to perform varint skipping instead of varint parsing is not\nworth complicating the field handler protocol).\n\nIn contrast to `DynamicFieldCopier()`, `DynamicFieldSkipper()` field predicate\nreturns `bool` instead of `std::optional\u003cint\u003e`, because returning a destination\nfield number is not applicable.\n\nIn contrast to `AnyFieldCopier()`, `AnyFieldSkipper()` is not provided because\nskipping remaining fields is the implicit default.\n\nIn contrast to `UnboundFieldCopier()`, `UnboundFieldSkipper()` can reuse the\nimplementation of `FieldSkipper()`, because it does not need a destination field\nnumber.\n\nAlso, make public `FieldAccepted` and `FieldAcceptedIf` for dynamic field\nhandlers which carry no extra information about the field being accepted. The\nfield handler protocol requires an API which fits `std::unique_ptr` and\n`std::optional` but not `bool`. These types are extracted from a private\nimplementation detail of `DynamicFieldHandler()`. They are used by\n`DynamicFieldSkipper()` too.\n\nAlso, fix embarrassing compile errors in `FieldHandlerWrapper()` for dynamic\nfield handlers.\n\nPiperOrigin-RevId: 914263217\n",
