Summary0002315: xdebug_dump_superglobals() leaks memory
Description

xdebug_dump_superglobals() calls xdebug_get_printable_superglobals() twice and never frees the memory.
It should only call the function once and free the memory.

Steps To Reproduce

Compile PHP with ASAN, and run the following command:

php run-xdebug-tests.php -d xdebug.mode=debug -d zend_extension=modules/xdebug.so -d zend_extension=modules/opcache.so -d opcache.enable=1 -d opcache.enable_cli=1 -d opcache.jit=disable --show-diff --asan tests/base/bug01266.phpt
Additional Information

I found this while exploring the xdebug code base. I have a local fix ready that I will PR.
The contribution guidelines told me to make an issue first so I'm doing that.
