The custom allocation API for libxml2 is deprecated starting in macOS
Sequoia 15.4, iOS 18.4, tvOS 18.4, visionOS 2.4, and tvOS 18.4.
Disable the memory function override for libxml2 when
LIBXML_HAS_DEPRECATED_MEMORY_ALLOCATION_FUNCTIONS is defined as Apple
broke the system-wide libxml2 starting with macOS Sequoia 15.4.
