[php-src] PR #24360: Fix -Wint-to-pointer-cast warnings in the CALL VM on 32-bit

Pull Request: https://github.com/php/php-src/pull/24360 Author: marc-mabe ZEND_VM_ENTER_BIT tags the opline returned by CALL VM handlers. It is 1ULL so that ~ZEND_VM_ENTER_BIT keeps the upper half of 64-bit pointers, but on 32-bit platforms it widens the tagged pointer expressions to 64 bits, and casting those back to a pointer warns. This breaks --enable-werror builds where no global VM registers are used, e.g. arm32, or i386 with --disable-gcc-global-regs, which also hits the copy of the definition in the JIT. Use (uintptr_t)1 instead, which is exactly pointer-sized everywhere.
