Initial compatability support for PHP8.2 for readonly classes.

[kschatzle]

readonly classes will throw a ClassMirrorException until supported.

What's the error currently when we try and extend readonly classes?

What's the error currently when we try and extend readonly classes?

PHP Fatal error:  Non-readonly class Double\Fixtures\Prophecy\ReadOnlyClass\P1 cannot extend readonly class Fixtures\Prophecy\ReadOnlyClass in %s/src/Prophecy/Doubler/Generator/ClassCreator.php(49) : eval()'d code on line 2

I have pushed a patch to support doubling readonly class.
It's available through this PR: #571

Would there be a mean of communication (chat/mailing list) to coordinate efforts around supporting 8.2?
I'd gladly help, however don't want to create noise if you have already defined a strategy (first convert fatal error into proper exception, then support feature one by one, for instance).

Thanks for the effort, I've merged #571 so this is not needed

@gquemener on the subject of coordination I'd prefer Issues here
