bors bb85bcaca9 Auto merge of #96195 - sunfishcode:sunfishcode/handle-or-error-type, r=joshtriplett
Define a dedicated error type for `HandleOrNull` and `HandleOrInvalid`.

Define `NullHandleError` and `InvalidHandleError` types, that implement std::error::Error, and use them as the error types in `HandleOrNull` and `HandleOrInvalid`,

This addresses [this concern](https://github.com/rust-lang/rust/issues/87074#issuecomment-1080031167).

This is the same as #95387.
