random: Validate that the arrays do not contain extra elements when unserializing (#9458)
* Apply `var_dump()` in 02_engine/all_serialize_error.phpt

This ensures that an undetected serialization error is clear identifiable in the output.

Fix GH-9186 @strict-properties can be bypassed using unserialization (#9354)
* Emit deprecation warnings when adding dynamic properties to classes during unserialization - this will become an Error in php 9.0.
  (Adding dynamic properties in other contexts was already a deprecation warning - the use case of unserialization was overlooked)
* Throw an error when attempting to add a dynamic property to a `readonly` class when unserializing
* Add new serialization methods `__serialize`/`__unserialize` for SplFixedArray to avoid creating deprecated dynamic
  properties that would then be added to the backing fixed-size array
* Don't add named dynamic/declared properties (e.g. $obj->foo) of SplFixedArray to the backing array when unserializing
* Update tests to declare properties or to expect the deprecation warning
* Add news entry

Clean up the implementation of Randomizer::__construct() (#9222)
* Verify that the engine doesn't change in construct_twice.phpt

* Clean up the implementation of Randomizer::__construct()

Instead of manually checking whether the constructor was already called, we
rely on the `readonly` modifier of the `$engine` property.

Additionally use `object_init_ex()` instead of manually calling
`->create_object()`.

Clean up nested exceptions without value-add in ext/random (#9211)
* Remove exception in Randomizer::shuffleBytes()

The only way that `php_binary_string_shuffle` fails is when the engine itself
fails. With the currently available list of engines we have:

- Mt19937            : Infallible.
- PcgOneseq128XslRr64: Infallible.
- Xoshiro256StarStar : Infallible.
- Secure             : Practically infallible on modern systems.
                       Exception messages were cleaned up in GH-9169.
- User               : Error when returning an empty string.
                       Error when seriously biased (range() fails).
                       And whatever Throwable the userland developer decides to use.

So the existing engines are either infallible or throw an Exception/Error with
a high quality message themselves, making this exception not a value-add and
possibly confusing.

* Remove exception in Randomizer::shuffleArray()

Same reasoning as in the previous commit applies.

* Remove exception in Randomizer::getInt()

Same reasoning as in the previous commit applies.

* Remove exception in Randomizer::nextInt()

Same reasoning as in the previous commit applies, except that it won't throw on
a seriously biased user engine, as `range()` is not used.

* Remove exception in Randomizer::getBytes()

Same reasoning as in the previous commit applies.

* Remove exception in Mt19937::generate()

This implementation is shared across all native engines. Thus the same
reasoning as the previous commits applies, except that the User engine does not
use this method. Thus is only applicable to the Secure engine, which is the
only fallible native engine.

* [ci skip] Add cleanup of Randomizer exceptions to NEWS

Unify ext/random unserialize errors with ext/date (#9185)
* Unify ext/random unserialize errors with ext/date

- Use `Error` instead of `Exception`.
- Adjust wording.

* Make `zend_read_property` silent in `Randomizer::__unserialize()`

Having:

> Error: Typed property Random\Randomizer::$engine must not be accessed before
> initialization

is not a value-add in this case.

* Insert the actual class name in the unserialization error of Engines

* Revert unserialization failure back to Exception from Error

random: split Randomizer::getInt() without argument to Randomizer::nextInt()
Since argument overloading is not safe for reflection, the method needed
to be split appropriately.

Remove ->last_unsafe from php_random_status (#9132)
Whenever ->last_unsafe is set to `true` an exception has been thrown. Thus we
can replace the check for `->last_unsafe` with a check for `EG(exception)`
which is a much more natural way to ommunicate an error up the chain.

Fix memory leak on Randomizer::__construct() call twice (#9091)
When Radomizer::__construct() was called with no arguments, Randomizer\Engine\Secure was implicitly instantiate and memory was leaking.
