Implement Stringable automatically for internal classes

Requiring all internal classes (including those from 3rd-party
extensions) to implement Stringable if they provide __toString()
is too error prone. Case in point, our _ZendTestClass test class
was not doing so, resulting in preloading test failures after
recent changes.

Instead we automatically implement Stringable, the same as we do
for userland classes. We still allow explicit implementations,
but ignore them (normally they would result in an error due to
duplicate interface implementation). Finally, we need to be
careful about not trying to implement Stringable on Stringable
itself.

In some cases this changes the interface order, in particular the
automatic Stringable implementation will now come first.

Make Exception::$previous a typed property

Exception::$previous is a private property, so we can add a type:

private ?Throwable $previous = null;

Make Exception::$trace typed array property

This is a private property, so we are allowed to add a type.
The new declaration of the property is:

private array $trace = [];

Make Exception::$trace typed array property

This is a private property, so we are allowed to add a type.
The new declaration of the property is:

private array $trace = [];

This ensures that Exception::getTrace() does indeed return an array.

Userland code that was modifying the property through refleciton
may have to be adjusted to assign an array (instead of null,
for example).

Closes GH-5636.

Revert removal of private __clone() methods

I thought these were redundant, because we already NULL out the
clone_obj object handler. However, it turns out that reflection is
using private __clone() to determine clonability (isCloneable) for
the case where we only have a class, rather than an object.

As such, removing these methods would be a BC break.
