This information is available in the regular stack but since that's
hidden behind an expando and our appended stack to logs is not hidden,
it hides the most important frames like the name of the current
component.
This is closer to what happens to the native stack.
We only include stacks if they're within a ReactFiberCallUserSpace call
frame. This should be most that have a current fiber but this is
critical to filtering out most React frames if the regular node_modules
filter doesn't work.
Most React warnings fire during the rendering phase and not inside a
user space function but some do like hooks warnings and setState in
render. This feature is more important if we port this to React DevTools
appending stacks to all logs where it's likely to originate from inside
a component and you want the line within that component to immediately
part of the visible stack.
One thing that kind sucks is that we don't have a reliable way to
exclude React internal stack frames. We filter node_modules but it might
not match. For other cases I try hard to only track the stack frame at
the root of React (e.g. immediately inside createElement) until the
ReactFiberCallUserSpace so we don't need the filtering to work. In this
case it's hard to achieve the same thing though. This is easier in RDT
because we have the start/end line and parsing of stack traces so we can
use that to exclude internals but that's a lot of code/complexity for
shipping within the library.
For example in Safari:

Ideally warnOnUseFormStateInDev and useFormState wouldn't be included
since they're React internals. Before this change, the Counter.js line
also wasn't included though which points to exactly where the error is
within the user code.
(Note Server Components have V8 formatted lines and Client Components
have JSC formatted lines.)
