FR: Include document path in error messages

**Is your feature request related to a problem? Please describe.**
When getting an error like
```
Error: Value for argument "data" is not a valid Firestore document. Cannot use "undefined" as a Firestore value (found in field "xyz"). If you want to ignore undefined values, enable `ignoreUndefinedProperties`.
```
often it's hard to understand in which document the error would appear, especially when writing lots of documents in one execution.

**Describe the solution you'd like**
Include the document path in all errors, e.g.:
```
Error: Value for argument "data" of document "foo/bar/baz/bat" is not a valid Firestore document. Cannot use "undefined" as a Firestore value (found in field "xyz"). If you want to ignore undefined values, enable `ignoreUndefinedProperties`.
```

**Describe alternatives you've considered**
Manually log all the document paths before executing a Firestore query, which can also spam the logs.
