* Add support for `cause:` argument to `Fiber#raise` and `Thread#raise`.

The implementation behaviour is consistent with `Kernel#raise` and
`Exception#initialize` methods, allowing the `cause:` argument to be
passed to `Fiber#raise` and `Thread#raise`. This change ensures that
the `cause:` argument is handled correctly, providing a more consistent
and expected behavior when raising exceptions in fibers and threads.

[Feature #21360]

* Shared specs for Fiber/Thread/Kernel raise.

[Feature #13557]

Setting the backtrace with an array of strings is lossy. The resulting
exception will return nil on `#backtrace_locations`.

By accepting an array of `Backtrace::Location` instance, we can rebuild
a `Backtrace` instance and have a fully functioning Exception.
