Fix macOS 15 Intel RELEASE builds by disabling JIT

Disable opcache JIT for macOS 15 Intel (x86_64) RELEASE builds to work around Clang 17 tail call optimization bug that causes compilation failure in zend_jit_vm_helpers.c.

The error occurs due to incompatibility between PHP JIT musttail attributes and Clang 17's tail call elimination.

- DEBUG builds on macOS 15 Intel: JIT remains enabled
- ARM64 builds (macOS 14): unaffected, JIT works normally
- Other platforms: no changes
