refactor[devtools]: forbid editing class instances in props (#26522)

## Summary
Fixes https://github.com/facebook/react/issues/24781

Restricting from editing props, which are class instances, because their
internals should be opaque.

Proposed changes:
1. Adding new data type `class_instance`: based on prototype chain of an
object we will check if its plain or not. If not, then will be marked as
`class_instance`. This should not affect `arrays`, ..., because we do
this in the end of an `object` case in `getDataType` function.

Important detail: this approach won't work for objects created with
`Object.create`, because of the custom prototype. This can also be
bypassed by manually deleting a prototype ¯\\\_(ツ)_/¯
I am not sure if there might be a better solution (which will cover all
cases) to detect if object is a class instance. Initially I was trying
to use `Object.getPrototypeOf(object) === Object.prototype`, but this
won't work for cases when we are dealing with `iframe`.


2. Objects with a type `class_instance` will be marked as unserializable
and read-only.

## Demo
`person` is a class instance, `object` is a plain object
