JIT/AArch64: [macos] Fix arguments to variadic function (#7023)

zend_throw_error() and zend_error() are variadic functions. In Linux,
arguments are passed in registers, whereas they must be put on stack in
Macos [1][2].

In this patch:
1. preprocessor macro "__APPLE__" is used to distinguish the OS.
2. the third argument "CARG3" is the only variadic argument and put on
stack.
3. the invocation of zend_error() is converted back to regular call in
zend_jit_undefined_offset_stub() and zend_jit_undefined_index_stub().

With this patch, all ~4k test cases can pass for "nonZTS+CALL"
functional/tracing JIT with Macos Apple Silicion.
