ErrorBoundary should catch custom Error

[alirezabonab]

I have logics in the ActionFunction method that validates the form input. If the input is invalid, it will throw a Custom Error which extends Error. The CustomError will have more detail about what was wrong and I want to get that CustomError in the ErrorBoundary method.

I looked into the source code and it seems that it serializes and deserializes the error object and in the process of serialization and deserialization it only takes the message and stack properties.

It would be awesome to be able to catch Custom Errors through ErrorBoundaries cause there is no other way to get details about what happened in the ErrorBoundary right now.

There is an open PR to include the error name prop for custom errors.

#3719

The issue with PR is that it is not handling the deserializeError, And because of the the implementation is not helpful. considering serializing and deserializing does not take any types eventually it loses types and with current implementation it is not possible to make it type friendly.

That's fine. I'm just saying somebody is working on supporting custom errors. The PR may need more work.
