Avoid PHP 8.3 FFI deprecations (fixes #226)

[uuf6429]

This probably isn't the ideal way (the ideal way would be dependency injection), but it's fast and backward-compatible.
I tested this briefly on my machine and it seemed to work well.

@jcupitt can this be merged soon? :)

Sorry! I'll spend some time on this later today.

This looks good, and you say, nice and simple.

We just need to fix the unit test failure with php 8.3. I'm not sure what's causing the stack overflow and I don't have php8.3 installed or I'd investigate myself :(

I saw that on my mac and thought it was just a mac fluke. I'll investigate it myself, no problem.

Looking for merging this...

The salient part of the unit test failure is:

PHP Fatal error:  Throwing from FFI callbacks is not allowed in /home/runner/work/php-vips/php-vips/src/VipsOperation.php on line 308

https://github.com/libvips/php-vips/actions/runs/7758073643/job/21184045945#step:6:42

I assume it's due to the use of assert() within GObject::getMarshaler(). PR #233 would probably fix that.

Let's merge and do any final tweaks in a followup. Thanks for doing this work, and sorry for being so slow :(

i have some problem like that :
PHP Fatal error: Maximum call stack size of 8339456 bytes (zend.max_allowed_stack_size - zend.reserved_stack_size) reached. Infinite recursion?
When will it be fixed ?
And there is no way until it is fixed ?

@Tak-Pesar, this is a PHP bug, you need to disable stack size checking, have a look at the php-vips README.
