Zend/zend_call_stack.h: fix missing include on Windows (clang compat)

[dunglas]

clang is stricter than Visual Studio and requires an explicit include. This patch fixes building on Windows with clang-cl.

Details

 Zend\zend_call_stack.h(42,9): error: call to undeclared library function '_AddressOfReturnAddress' with type 'void *(void)'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]

   42 |         return _AddressOfReturnAddress();

      |                ^

Zend\zend_call_stack.h(42,9): note: include the header <intrin.h> or explicitly provide a declaration for '_AddressOfReturnAddress'
